Question

correctly identify all movements facilitated by the biceps brachii. select all that apply. answers: a - e a flexes forearm at the elbow joint b flexes arm at the shoulder c adduct thigh at hip joint d flexes leg at the knee joint e extends thigh at hip joint

Explanation:

The biceps brachii is a muscle in the upper arm. It has two main functions related to arm movement. Firstly, it flexes the forearm at the elbow joint (Option A). This is the classic "bicep curl" movement. Secondly, it also assists in flexing the arm at the shoulder joint (Option B). Options C, D, and E are related to leg and thigh movements, which are not functions of the biceps brachii. The biceps brachii is an arm - specific muscle, so movements involving the hip and knee joints (Options C, D, E) are incorrect as they pertain to lower - body muscles.

Answer:

A. Flexes forearm at the elbow joint, B. Flexes arm at the shoulder
