the deltoid originates in the acromion and spine of the scapula and the acromial end of the clavicle. where does it insert?
a medial condyle
b greater tubercle of the humerus
c deltoid tuberosity
d radial tuberosity
e soleus

Explanation:

To determine where the deltoid muscle inserts, we recall anatomical knowledge: the deltoid muscle originates from the acromion, spine of the scapula, and acromial end of the clavicle. Its insertion point is the deltoid tuberosity of the humerus. Let's analyze the options:

• Option A: The medial condyle is related to other muscles (e.g., for forearm or leg movements), not the deltoid.
• Option B: The greater tubercle of the humerus is the insertion for rotator cuff muscles, not the deltoid.
• Option C: The deltoid tuberosity is the correct insertion site for the deltoid muscle.
• Option D: The radial tuberosity is the insertion for the biceps brachii, not the deltoid.
• Option E: The soleus is a calf muscle, unrelated to the deltoid.

Answer:

C. deltoid tuberosity
