Question

All of the following statements accurately identify the origin of a head of the triceps brachii except?

a) Infraglenoid tubercle of the scapula
b) Posterior surface of the humerus
c) Medial and lateral intermuscular septa
d) Radial groove of the humerus

Answer 1

The origin of a head of the triceps brachii is the infraglenoid tubercle of the scapula, the posterior surface of the humerus, and the medial and lateral intermuscular septa. The radial groove of the humerus is not the origin.

Step-by-step explanation:

The origin of a head of the triceps brachii is the infraglenoid tubercle of the scapula, theposterior surface of the humerus, and the medial and lateral intermuscular sept. The radial groove of the humerus does not accurately identify the origin of a head of the triceps brachii.
