What does the humerus do in animals?
Humerus, long bone of the upper limb or forelimb of land vertebrates that forms the shoulder joint above, where it articulates with a lateral depression of the shoulder blade (glenoid cavity of scapula), and the elbow joint below, where it articulates with projections of the ulna and the radius.
Does a horse have a humerus?
The humerus sometimes known as the upper arm, long bone of the arm or arm bone might not make you laugh but it is a very important part of your skeleton. The humerus is a single bone in both horses in humans. It is between the shoulder blade and forearm.
What is the humerus bone?
The humerus is the arm bone between your shoulder and your elbow. There are two types of humerus fractures based on the location of the break(s). Trauma from a fall or accident are often the cause of this type of fracture.
What is the function of the humerus in a cat?
It lies along the lower border of the scapula, and it passes through the upper arm, across the upper end of muscles of the upper arm. It originates at the spine of the scapula and inserts at the deltoid ridge. Its action is to raise and rotate the humerus outward.
What are the features of the humerus?
The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below.
What bone does the humerus articulate with?
scapula
The humerus is a long bone of the upper limb, which extends from the shoulder to the elbow. The proximal aspect of the humerus articulates with the glenoid fossa of the scapula, forming the glenohumeral joint.
Can you move your arm with a broken humerus?
A fractured humerus or upper arm is extremely painful, and the patient may not be able to move their arm. Sometimes, the radial nerve (one of the main nerves in the arm) may be injured. This happens about 15% of the time. It is more common with fractures that happen closer to the base of the bone.
What does a broken humerus feel like?
Symptoms of a humerus fracture Symptoms can include pain, swelling, and bruising. If the bone breaks through the skin, bleeding can occur at the site. It may be hard to move and use the shoulder, arm, or elbow as you would normally.
What is unique about the humerus?
The humerus is the largest bone in the entire upper extremity. The top of the humerus joins with an area called the glenoid fossa on the scapula or shoulder blade. The meeting of these bones allows for the wide range of motion which is possible at the shoulder joint, along with movement at the elbow.
What is an example of humerus?
The long bone of the arm or forelimb, extending from the shoulder to the elbow. The bone of the upper arm or forelimb, extending from the shoulder to the elbow. The long bone of the arm or forelimb, extending from the shoulder to the elbow.
What is the function of the head of the humerus?
In situations such as these, medical intervention can assist with bone lengthening techniques to achieve a more normalized and functional appearance of the bone. The head of the humerus makes up a portion of the ball-and-socket shoulder joint. This area also serves as the insertion point for muscles which make up the shoulder girdle.
What kind of bone is the humerus bone?
The equine humerus is a relatively short, compact bone with a significant muscular covering and complex surface topography. Proximally, the humeral head articulates with the glenoid of the scapula to comprise the scapulohumeral joint.
What is the function of the femur in a horse?
The pelvis or pelvic girdle serves to protect the inner organs, including the uterus. The femur, which is a large bone, connects with the pelvis at the hip joint and with the hind leg at the stifle joint. The tibia forms the upper part of the hind limb from the stifle to the hock.
What kind of bones does a horse have?

What kind of muscles does a horse have?
If this is well developed the horse is working in a good outline. Flexes the shoulder and pulls the foreleg back. Helps pull the foreleg foreward. Flexes the toe and knee and extend the elbow. Muscles of the trunk, back and ribs. Muscles support the spine together with 3 ligaments and abdominal muscles.

Where does the humerus join the ulna and radius?
The humerus forms the elbow joint with the ulna and radius. Where they join, the humerus has a deep groove called the olecranon fossa. This is where the olecranon process (the free end of the ulna) will enter when the weight is placed on the leg, locking the joint and so stabilize the entire leg.
