What does the Omotransversarius muscle do?
The omotransversarius is a straplike muscle, which advances and adducts the forelimb, as well as flexes the neck laterally. It covers the transverse processes of the cervical vertebrae, lying to their side.
What artery supplies the Omotransversarius?
and inferior cervical arteries
MUSCLES OF PECTORAL GIRDLE – OMOTRANSVERSARIUS Action: To pull the lower angle of the scapula forwards and upwards and to tense the scapular fascia. Blood supply: Superior and inferior cervical arteries.
Do horses have quadriceps?
Horses, however, have much bigger quadriceps, the large muscles above the knee that make up the thigh, and three patella ligaments compared to only one in humans.
What is this extrinsic muscle?
Definition. A group of muscles lying superficially on a structure, in contrast to intrinsic muscles, which are located deeply. Supplement. For instance, the extrinsic muscles of the tongue include genioglossus muscle, hyoglossus muscle, styloglossus muscle, and palatoglossus muscle.
What is the Brachiocephalicus?
The brachiocephalicus is a long and flat, complex of muscles that extends from the lower half of the humeral shaft to the head and neck. The muscle divides into two parts at the clavicular intersection. This is also the point of origin for all the muscles that make up the brachiocephalicus.
What is the function of the serrated face of the scapula?
The serratus ventralis thoracic muscle inserts on the serrated surface of the scapula to draw the scapula backwards and the chest upwards and is innervated by the long thoracic nerve. The serratus ventralis thoracic and the serratus ventralis cervix muscles act like a supportive sling between the forelimbs.
Where are quadriceps on a horse?
The quadriceps muscle has four components; the rectus femoris, vastus lateralis, vastus medialis and vastus intermedius which originate on the body of the ilium, lateral femur, medial femur and cranial femur respectively. The quadriceps insert on the patella and transmit their action through the patellar ligaments.
What are extrinsic muscles in animals?
Extrinsic muscles run from one region of the body to another and alter the position of the whole part, e.g. a limb, in relation to the other. The muscles that attach the foreleg of the dog to the trunk are extrinsic muscles; they move the whole foreleg in relation to the trunk.
How many extrinsic muscles are there?
Description: The extraocular muscles are the six muscles that control movement of the eye (Superior rectus, Inferior rectus, Lateral rectus, Medial rectus, Superior oblique and Inferior oblique) and one muscle that controls eyelid elevation (levator palpebrae).
What is the omotransverse muscle?
Description. The omotransverse muscle (Musculus omotransversarius) is a strong cord-like muscle between the wing of the atlas, the transverse process of the axis and the fascia covering the lateral aspect of the shoulder joint and the spine of the scapula. Its ventral border is fused to the cervical part of the trapezius muscle and in the horse,…
What is Omotransversarius fascia?
Omotransversarius Fascia of lateral shoulder region By separate digitations onto transverse processes of C2–4 Limb protraction and lateral flexion of neck Brachiocephalicus cranial and caudal Mastoid process and transverse processes of varying proximal cervical vertebrae Deltoid tuberosity between biceps brachii and brachialis
Is a thoracic limb extrinsic muscle dissection performed on fresh horse cadavers?
A thoracic limb extrinsic muscle dissection was performed on six fresh horse cadavers euthanased for reasons unrelated to musculo-skeletal pathology and obtained from the Royal Veterinary College, UK. Body mass, height (from dorsal thoracic vertebral spines to ground) and breed of each cadaver was obtained from hospital records (Table 1).
Why is Brachiocephalicus and Omotransversarius considered as one (Bo)?
The data from subject E were not used to calculate means as its body mass was approximately half that of the other subjects. It was not possible to separate brachiocephalicus and omotransversarius at their origin and thus the muscles were considered as one (BO).
