8. In human anatomy, the
clavicle or collarbone is a long
bone that serves as a strut
between the shoulder blade
and the sternum or
breastbone.There are two
clavicles, one on the left and
one on the right.The clavicle
is the only long bone in the
body that lies horizontally.
20. SCAPULA
The scapula (plural
scapulae or scapulas) or
shoulder blade is the bone
that connects the humerus
(upper arm bone) with the
clavicle (collar bone).
25. AXILLA
The Axilla (also,
underarm, oxter, or,
colloquially, armpit) is
the area on the human
body directly under the
joint where the arm
connects to the
shoulder. It also
provides the under-arm
sweat gland.
34. AXILLARY ARTERY
The axillary artery is often referred to as
having three parts, with these divisions
based on its location relative to the Pectoralis
minor muscle, which is superficial to the
artery.
First part - the part of the artery above the
pectoralis minor
Second part - the part of the artery that lies
behind the pectoralis minor
Third part - the part of the artery below the
pectoralis minor.

– Lateral thoracic artery.
■ Third part (3 branches)
– Subscapular artery

The brachial plexus is a
network of nerves, running
from the spine, formed by
the anterior rami of the
lower four cervical nerves
and first thoracic nerve (C5–
C8,T1).The brachial plexus
passes through the
cervicoaxillary canal in the
neck, over the first rib, and
into the axilla (armpit
region), where it innervates
the upper limbs and some
neck and shoulder muscles.
