Movement at the elbow by the forearm away from the shoulder is accurately described by the term "flexion".

False

Supination refers to internal rotary movements of the radius on the ulna.

False

The insertion of the brachialis muscle is the coracoid process of the ulna.

False

The insertion of the brachioradialis muscle is the proximal end of the radius at the styloid process.

False

The lateral supracondylar ridge is an anatomical landmark located on the ulna.

False

The olecranon process is located on the medial aspect of the ulna.

False

The scapula and clavicle serve as the proximal attachments for the muscles that flex and extend the elbow.

False

While in the anatomical position the radius is medial with respect to the ulna.

False
