2 points
the rectus abdominis originates in the
and inserts into the coastal cartilage (ribs 5 - 7) and the xiphoid
process.
a t1 - t12 vertebrae
b coracoid process
c deltoid tuberosity
d pubis bone and pubis symphysis
e brachialis

Explanation:

To solve this, we recall the anatomy of the rectus abdominis. The rectus abdominis muscle originates from the pubis bone and pubis symphysis. Let's analyze the options:

• Option A (T1 - T12 vertebrae) is incorrect as that's not the origin of rectus abdominis.
• Option B (coracoid process) is related to shoulder muscles, not rectus abdominis.
• Option C (deltoid tuberosity) is for the deltoid muscle's insertion, not relevant here.
• Option D (pubis bone and pubis symphysis) is the correct origin of rectus abdominis.
• Option E (brachialis) is an arm muscle, irrelevant.

Answer:

D. pubis bone and pubis symphysis
