Do you want to know about the abdominal muscles of goats?
If yes, then you are in the right place. In this article, I will discuss goat’s abdominal muscles.
If you are interested, I request that you stay with me and continue to read this article.
In this article, I will also try to cover abdominal muscle anatomy, abdominal muscle function, transverse abdominis, external oblique, internal oblique, external oblique muscle, rectus abdominis muscle, and transverse abdominis exercises in detail.
Okay, let’s start to know
What do we know in this article? (Abdominal Muscles of Goat)
- #1. List of abdominal muscles of goat
- #2. Details about abdominal muscles
- #3. Cutaneous muscles
- #4. Flank
- #5. Paralumbar fossa
- #6. Linea alba
- #7. Prepubic tendon
- #8. Inguinal canal and abdominal press
Okay, fine. Let’s discuss this in detail.
“You may watch the video carefully. Please take advantage of every single second. I hope this video will help you learn and identify all the abdominal muscles of goats.”
Muscles of the Goat
Now, I am going to discuss the abdominal muscles of goats.
The lateral and ventral walls of the abdomen are formed mainly by abdominal muscles. The names of the abdominal muscles depend on their fiber direction.
In the picture below, some muscles and their fibers are directed differently.
Okay, notice this muscle fiber (shown in the picture); they are directed ventrally and caudally, or you may consider it as oblique direction. Again, this muscle is located at the external aspect.
So you have two terms – oblique direction, second – located externally; so, you may call this muscle obliquus externus, and as it is the muscle of the abdomen, you may also call abdominius muscle;
Fully – obliqqus externus abdominis muscle.
Again, notice this muscle (shown in the picture). Its fibers are directed ventrally and cranially and located beneath the obliqqus externus abdominis muscle. So, you may call this muscle the obliquus internus abdominis muscle.
The fiber of this muscle (shown in the picture) is directed vertically and located at the deep face of the obliquus internus and rectus abdominis muscles. It is called the transverse abdominis muscle.
And finally, notice this muscle (please find it in the picture). It is located at the ventral wall of the abdomen, and its fibers are directed longitudinally or cranial to the caudal direction or straight. This is called rectus abdominis muscle.
So, goats have four main abdominal muscles, and they are –
- #1. Obliquus externus abdominis muscle
- #2. Obliquus internus abdominis muscles
- #3. Transverse abdominis muscle and
- #4. Rectus abdominis muscle
Again, you will find some other important muscles, like
Cremaster muscle.
Preputialis cranialis and caudalis muscles.
Okay, fine. Let’s continue this article.
Before going into details about these muscles, I would like to memorize some topics, such as the structure of the abdominal region, flank, paralumbar fossa, linea alba, and prepubic tendon.
In the abdomen, you will find these structures serially
#1. First, Skin.
#2. Second, the Cutaneous muscle, which is called the cutaneous trunci muscle
#3. Then, there is the fascia (superficial fascia and deep fascia); the deep fascia is called the abdominal tunic.
#4. Fourth, Muscles and the parietal layer of the peritoneum.
Do you want to memorize about cutaneous muscles?
Okay, fine. Try to memorize –
This is a thin muscular layer that develops in the superficial fascia of an animal’s body. It is intimately or extensively adherent in great part to the skin.
The cutaneous muscle is well developed in ruminants and named according to the location at a certain region of the animal’s body.
# The facial part is called the muscle cutaneous faciei.
#In the cervical part, it is called muscle cutaneous colli.
#In the abdominal part, it is called muscle cutaneous trunci.
I hope you can understand.
Flank and Paralumbar fossa of goat
Okay, now let’s talk about the flank and paralumbar fossa.
The first flank, the flank, is the part of the lateral abdominal wall that is formed only of soft structures.
Okay, now what is paralumbar fossa?
Notice the triangular depression in the dorsal part of the flank. This depression is termed the paralumbar fossa.
Okay, very well. Now, you should know about the linea alba and prepubic tendon.
Linea alba and Prepubic tendon of goat
Okay, let’s talk about linea alba first.
It is a median white fibrous raphe that extends from the xiphoid cartilage to the prepubic tendon.
It is formed by the union of the aponeurosis of the obliquus externus, internus, and transverse abdominis muscles and partly by the rectus abdominis muscle.
Now, what is a prepubic tendon?
The rectus muscles are inserted into the cranial border of the pubic bone at the iliopubic eminences as a tendon.
These tendons are called prepubic tendons. The prepubic tendon is essentially the tendon of insertion of the two recti muscles.
Okay, now I am going to describe abdominal muscles in detail.
Details on abdominal muscles of goat
I will try to cover each muscle’s fiber direction, origin, insertion, blood supply, and nerve supply.
#1. Obliquus externus abdominis muscle
It is the most extensive, broad, and irregular triangular abdominal muscle.
Fiber is directed ventrally and caudally.
Origin:
This muscle originated from the lateral and caudal border of the 8th ribs and
Fascia over intercostal muscle
These are ribs, and these spaces are called intercostal spaces; again, these intercostal spaces are filled with muscles called intercostal muscles—intercostal externi and intercostal interni muscles.
Okay, now let’s talk about insertion.
This muscle is inserted into the coxal tuber, prepubic tendon, and linea alba.
Well. Now, the blood and nerve supplies of this muscle are insufficient.
If you notice, this muscle extends from the intercostal area to the lumbar area and again to the ventral abdomen.
This muscle is supplied by intercostal and lumbar arteries. Again, cranial branches of the deep circumflex iliac artery also supply this muscle.
I hope you have an idea about the spinal nerves.
Obliquus externus abdominis muscle is supplied by ventral branches of spinal nerves.
Which one?
Okay, stay with this article and continue to read it again.
As this muscle extends from the thoracic to the lumbar regions, it is supplied by ventral branches of a few thoracic and lumbar spinal nerves (let’s watch the video and find it).
The lateral cutaneous femoral nerve also supplies it.
Okay, well.
The blood and nerve supply for the rest of the three muscles is almost similar, as I mentioned above, for the obliquus externus abdominis muscle. So, I will not repeat these, okay?
Now, let’s talk about obliquus internus abdominis muscle.
#2. Obliquus internus abdominis muscle
It is located beneath the obliquus externus abdominis muscle and is also triangular.
The fibers are directed ventrally and cranially.
Origin.
It originated from a coxal tuber. This is the coxal tuber or tuber coxae.
It also originated from the deep lumbar fascia at the lateral border of the longissimus lumborum.
If you don’t know about longissimus lumborum muscle, don’t worry.
Let’s have a look (in a picture or in the video).
The larger long muscle above is called longissimus dorsi, and below this muscle, which is indicated by the forceps, is called longissimus lumborum.
I will discuss these muscles in detail.
The Longissimus lumborum is located in the lateral aspect of the ribs.
Insertion.
This muscle is inserted into the caudal border of the last rib, prepubic tendon, and linea alba.
Well. Let’s talk about the transverse abdominis muscle.
#3. Transverse abdominis muscle
They are located at the deep face of the obliquus internus abdominis and rectus abdominis muscles.
Fiber is directed vertically.
Originated from the transverse process of lumbar vertebrae and inserted into the linea alba and xiphoid cartilage.
Okay, now the rectus abdominis muscle.
It is confined to the ventral abdominal wall and extended from the sternum to the pubic bone.
The fibers are directed from cranial to caudal or longitudinally.
It is superficially related to the aponeurosis of the obliquus externus and obliquus internus abdominal muscles; again, deeply, it is related to the transverse abdominis muscle.
This muscle originates from the ventral and lateral surface of the sternum and is inserted into the prepubic tendon.
Fine.
Now, cremaster muscle.
It is regarded as the detached portion of the obliquus internus abdominis muscle, which separates as a slip of fleshy tissue and enters the inguinal canal.
If you don’t know about the inguinal canal, I would like to introduce it in very simple words and shortly. You will know in detail about the genital system.
Inguinal canal of goat
Inguinal canals are paired slit-like oblique passages or spaces through the caudal part of the abdominal wall lying on either side of the prepubic tendon.
Each canal has two openings – a deep inguinal ring and a superficial inguinal ring.
You should know about the contents of the inguinal canal both in male and female animals.
In the males, the contents are – the spermatic cord, vaginal tunic, cremaster muscle, external pudendal artery, and ilioinguinal and genitofemoral nerves.
Again, in females, the contents are external pudendal vessels and ilioinguinal and genitofemoral nerves.
Okay, well.
Now, the last topic of today’s article is abdominal press.
Abdominal press
Contraction of abdominal muscles and diaphragm muscles places pressure on the abdominal viscera and
This helps in micturition, defecation, forced expiration, coughing, and parturition.
These contractions of abdominal muscle and diaphragm on visceral organs are known as abdominal presses.
Is it not enough to learn abdominal muscles, abdominal muscle anatomy, abdominal muscle function, transverse abdominis, external oblique, internal oblique, external oblique muscle, rectus abdominis muscle, and transverse abdominis exercises?
