What is biceps brachii?
The biceps brachii is a large, thick muscle on the ventral portion of the upper arm. The muscle is composed of a short head (caput breve) and a long head (caput longum).

Where is the Sternocleidomastoid quizlet?
The sternocleidomastoid muscle is a two-headed neck muscle, which true to its name bears attachments to the manubrium of sternum (sterno-), the clavicle (-cleido-), and the mastoid process of the temporal bone (-mastoid).
What is the short head of the bicep?
The short head of the biceps brachii is the shorter and medial of the two bodies that form the biceps brachii muscle in the upper arm. Like the long head of the biceps brachii, the short head is a flexor and supinator of the elbow joint. At the shoulder joint, the short head aids in adduction of the humerus.
What is the origin of the biceps femoris?
The biceps femoris muscle, located in the posterior portion of the thigh, is composed of a long head that originates from the ischial tuberosity and a short head that originates at the linea aspera of the femur. The biceps femoris inserts at the lateral head of the fibula.
How many origins does the biceps brachii have?
The biceps brachii has two heads, or origins, which is where the ‘bi’ in biceps comes from. Both heads originate on the scapula, which is the technical name for the shoulder blade.
Does the biceps brachii muscle originate or insert on the humerus?
In human muscles: … Does the biceps brachii muscle originate or insert on the humerus? No, it originates on the scapula and inserts on the radius.
Is the biceps brachii anterior or posterior?
The biceps brachii is on the anterior side of the humerus and is the prime mover (agonist) responsible for flexing the forearm. It has two origins (hence the “biceps” part of its name), both of which attach to the scapula bone.
Where is the triceps brachii muscle located?
The triceps brachii is located in the dorsal compartment of the arm. The lateral intermuscular septum separates the dorsal part from the arm from the ventral part, which is where the flexors of the arm are (biceps, brachialis, and brachioradialis).
