Where Would You Find The Scapula Bone In A Horse?

The scapula is a plate of bone positioned on the side of the horse from the withers to the point of the shoulder, where it joins the upper arm bone (humerus) to form the shoulder joint.

Does a horse have a scapula?

The scapula is placed laterally at a 45 degree angle. It is much more mobile in horses compared to humans, the horse having many fewer scapular/shoulder issues. There is also a large piece of scapular cartilage dorsally, incorporated into the withers.

Where is the scapula located quizlet?

The infraspinous fossa (of the scapula) is a structural feature on the scapula bone (also known as the shoulder blade or shoulder bone).

Is the scapula attached to the skeleton on a horse?

Cartilage of scapula – Cartilago scapulae
The scapular cartilage (small in carnivores) is attached to the dorsal border of the scapula and may extend over the level of whiters (in horses). It serves for attachment of scapular muscles and may be partially calcified.

What is the function of the scapula in a horse?

Scapula. The scapula is a triangular flattened bone which glides over the rib cage. The length and angulation of the scapula (ideally 45°) determine the slope of the horse’s shoulder and the length of stride.

What is the scapula bone in animal?

The scapula (shoulder blade) is a flat bone lying against the cranial part of the lateral thoracic wall. The scapula presents: A costal surface (medial surface), facing the ribs that is hollowed by the shallow subscapular fossa occupied by the origin of the subscapular muscle.

Where does the scapula belong?

scapula, also called shoulder blade, either of two large bones of the shoulder girdle in vertebrates. In humans they are triangular and lie on the upper back between the levels of the second and eighth ribs.

Where is the base of the scapula?

The lateral border, or base, the shortest of the three, is slightly concave; its edge, thick and round, is continuous above with the under surface of the acromion, below with the neck of the scapula. It forms the medial boundary of the great scapular notch, which serves to connect the supra- and infraspinatous fossae.

What type of bone is the scapula quizlet?

It is a long bone with two ends. The superior end, or the head, is the rounded end and connects to the glenoid cavity of the scapula to form the shoulder joint. This is a ball and socket joint.

Is the scapula attached to the ribs?

Then, our scapula is anchored to the spine and ribcage via several different stabilizing muscles. Lastly, the rotator cuff travels from the surface of the scapula, crossing the glenohumeral joint to hold the ball into the socket.

What muscles attach to the scapula of a horse?

The first group of muscles attaching the scapula to the thorax are lie on the lateral and medial aspects of the scapula. These include the Trapezius, Omotransversarius, Rhomboideus, Latissimus Dorsi and Serratus ventralis.

Is scapula part of forelimb?

The long bones of the forelimb are indicated in Fig. 2.9. These comprise the scapula, humerus, radius, and ulna that measure 28.77 ± 1.64 (SD) mm, 45.46 ± 1.13 mm, 40.21 ± 1.32 mm, and 47.08 ± 1.40 mm in length, respectively.

What is the top of a horse’s shoulder called?

Withers
Withers: the highest point of the thoracic vertebrae, the point just above the tops of the shoulder blades, seen best with horse standing square and head slightly lowered; the height of the horse is measured at the withers.

Why is it called the scapula?

Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. The name derives from the Classical Latin word for trowel or small shovel, which it was thought to resemble.

What is the shoulder of a horse called?

Withers
Withers. The withers are at the top of the shoulder where the neck joins the body. The ‘lump’ seen on many horses is the top of the spiny process of the tallest thoracic vertebrae.

Is the scapula the breast bone?

Sternum And Scapula:
The sternum is a bone in the center of the chest that articulates with the ribcage. It is often called the chest or breast bone. There are actually two scapulae bones behind in the back where each arm connects to the pectoral girdle, often called the “shoulder blades.”

Is the scapula part of the shoulder?

The shoulder is extremely mobile and made up of several joints that work together. The scapula, clavicle and humerus are the bones of the shoulder. The glenohumeral joint is the main joint and is more like a golf ball sitting on a tee.

What is shoulder in when riding a horse?

Shoulder-in is a movement performed on three tracks, in which the horse’s shoulder is brought to the inside while the hind end stays on the wall. In a correct shoulder-in, the inside hind leg and outside fore leg step on the same track.

Is scapula in front or back?

The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.

How do you palpate the scapula?

The spine of the scapula can be best palpated if you strum it perpendicularly by moving your palpating fingers up and down across it as you work your way posteriorly and then medially.

What is the origin and insertion of scapula?

Origin and insertion
Levator scapulae originates from the transverse processes of the first four cervical vertebrae. The muscle fibers descend laterally to insert at the superior angle and medial border of scapula, between the superior angle and base of the spine of scapula.
