What structure connecting the pectoral muscle to the humerus?
The structure connecting the pectoral muscle to the humerus is the tendon of the pectoralis major muscle. This tendon attaches the muscle to the upper arm bone (humerus), allowing for movements like shoulder flexion, adduction, and medial rotation.
Is the clavicle medial to the humerus?
Yes, the clavicle, or collarbone, is medial to the humerus, or upper arm bone.The clavicle is medial to the humerus. The clavicle, or collarbone, is located closer to the midline of the body than the upper body of the arm is.
What is the term referring to a structure's position towards the midline of the body?
The term is "medial."
Which feature of the ear is most medial?
The cochlea is the most medial feature of the ear. It is a spiral-shaped structure responsible for hearing and contains the sensory cells that convert sound waves into electrical signals sent to the brain.
What is the most lateral distal part of the humerus?
Lateral epicondyle of the humerus.
What is the distal medial process of the humerus?
The trochlea is the medial process of the humerus. The humerus articulates with the ulna at the trochlea.
Is the sternum lateral to the humerus?
No. The sternum is superior to the descending colon.
What important structure passes below the medial condyle of the humerus?
The ulnar nerve passes below the medial condyle of the humerus through a structure called the cubital tunnel. This nerve is responsible for providing sensation to the pinky and half of the ring finger, as well as controlling certain hand muscles.
What structure connecting the pectoral muscle to the humerus?
The structure connecting the pectoral muscle to the humerus is the tendon of the pectoralis major muscle. This tendon attaches the muscle to the upper arm bone (humerus), allowing for movements like shoulder flexion, adduction, and medial rotation.
Is the medial epicondyle adjacent to trochlea?
The medial epicondyle (on the humerus) is located closet to the body when in the anatomical position and the trochlea (on the humerus) is located slightly laterally and inferior to the medial epicondyle.
Is the clavicle medial to the humerus?
Yes, the clavicle, or collarbone, is medial to the humerus, or upper arm bone.The clavicle is medial to the humerus. The clavicle, or collarbone, is located closer to the midline of the body than the upper body of the arm is.
Where do the flexors of the wrist originate?
Medial epicondyle of the humerus.
What muscle is the main antagonist of medial rotation of the humerus?
The main antagonist of medial rotation of the humerus is the infraspinatus muscle, one of the rotator cuff muscles. It works in opposition to the muscles that perform medial rotation, such as the subscapularis.
What is located on the distal aspect of the humerus?
The medial and lateral epicondyles are located on the distal apsect of the humerus. The distal humerus articulates with the radius and ulna.
Which bone of the upper limb has a medial and a lateral epicondile?
The humerus
Is the ulna medial?
The ulna is not a midline structure. It is, however, the most medial bone of the forearm.
Is the nose lateral to the scapula?
The humerus is lateral to the sternum. The sternum, or breastbone, is midline.
