What else can I help you with?
The coronoid fossa is on what side of the humerus?
The coronoid fossa is located on the anterior side of the humerus, which is the side facing towards the front of the body.
Is the coronoid fossa on the lateral and posterior side of the humerus?
No, the coronoid fossa is on the lateral and anterior aspect of the humerus. It receives the coronoid process of the ulna during flexion of the elbow.
What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
Where on the humerus is the flexor of the elbow?
The primary flexor of the elbow is the biceps brachii, which originates from the scapula and attaches to the radial tuberosity on the radius, not directly on the humerus. However, the brachialis, another key flexor, originates from the anterior surface of the humerus, specifically the distal half of the shaft. It inserts onto the ulnar tuberosity and coronoid process of the ulna, contributing significantly to elbow flexion.
Anterior depression superior to the trochlea that receives part of the ulna whenthe forearm is flexed?
Olecranon fossa receives when extended Coronoid fossa receives it when flexed
Does the humerus has a coronoid fossa?
yes
The coronoid process articulates with what depression on the distal end of the humerus?
The depression in the scapula can be either one of four different structures; the supraspinatus fossa, the infraspinatus fossa, the subscapular fossa, or the glenoid fossa. The problem is that none of these articulate with the ulna. The bone you are probably looking for is the humerus, and it articulates with the last one I mentioned, the glenoid fossa.
What bony landmark can help you locate the brachialis?
The brachialis muscle can be located by identifying the distal humerus, specifically the anterior aspect of the lower half of the humerus. The muscle lies deep to the biceps brachii and is primarily attached to the coronoid process of the ulna. Palpating the area just medial to the biceps tendon can also help in identifying the brachialis.
Name the depression on the ulna into which the humerus inserts?
The depression on the ulna into which the humerus inserts is called the trochlear notch. This forms the hinge joint known as the elbow joint.
What bone do the muscles of the rotator cuff originate?
The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
Name a muscle that is a synergistic to the biceps brachii during elbow flexing?
Brachialis - attaches from the anterior proximal humerus to the coronoid process of the ulna - strong flexor of the elbowBrachioradialis - attaches from the lateral supracondylar ridge of the humerus to the distal styloid of the radius - weak flexor of the elbow
What muscle originates on scapula and proximal humerus and inserts on olecranon process?
The triceps originates on the scapula and proximal humerus and inserts on the olecranon process. The muscles has three heads (hence its name) so it has multiple origins.
