Question

question 5
the biceps brachii originates in the ______________ and inserts into the radial tuberosity.
a mastoid process
b coracoid process
c deltoid tuberosity
d tarsals
e brachialis

Explanation:

To solve this, we recall the anatomy of the biceps brachii. The biceps brachii has its origin at the coracoid process (and also the supraglenoid tubercle, but among the options, the coracoid process is the correct origin - related option here). The mastoid process is related to neck muscles, deltoid tuberosity is for the deltoid muscle, tarsals are in the foot, and brachialis is a different muscle. So the correct origin for biceps brachii (among these options) is the coracoid process.

Answer:

B. coracoid process
