The three anatomical part of mammary gland
Cutaneous layer
This anatomical part of the modified skin gland(mammary gland) contain 15-20 lobes
Parenchyma or Glandular tissue
The lobes of the mammary gland are drained by

Axillary artery
Axillary vein
On the left side of the body subclavian Artery branches off
On the right side of the body subclavian Artery branches off
Brachiocephalic Artery
The border of axillary Artery are
Lateral border of 1st rib
lateral border of teres major
How many parts do the axillary artery have
Three part
The first part of axillary artery is medial to pectoralis minor muscle which give off
Superior or Supreme thoracic Artery
This artery supply blood to upper part of thoracic wall
Superior Thoracic Artery
The second part of axillary artery lie posterior to pectoralis minor muscle give off
Thoracoacromial artery
Lateral thoracic artery
These are the four branches of thoracoacromial artery
deltoid muscle
acromial muscle
pectoral muscle
The third part of axillary artery lie lateral to pectoralis minor muscle give off
Subscapular artery
Anterior humeral circumflex A
posterior humeral circumflex A
Subscapular Artery give off
Thoracodorsal Artery
circumflex Scapular Artery
This artery and nerve supply latissimus dorsi muscle, Serratus Anterior,Tere major muscle
Thoracodorsal Artery
Thoracodorsal Artery
This artery travel through the triangular space in the back
Circumflex scapular Artery
These Arteries encircle surgical neck of the humerus
Anterior humeral circumflex A
Posterior humeral circumflex A
This artery and nerve travel through quadrangular space in the back
Posterior humeral circumflex A
Axillary nerve
Brachial plexus are form by this part of spinal nerve
Ventral rami of the spinal nerve
The spinal nerve that make up the brachial plexus are
C 5-8
T 1
Spinal nerves are composed of how many pairs
31 pairs
The spinal nerves are
8 Cervical nerve
12 Thoracic nerve
5 Lumbar nerve
5 sacral nerve
1 Coccygeal nerve
The origin of the ventral root of the spinal nerve
Anterior horm
Ventral root spinal nerve carry these fibers
Efferent or Motor fiber
The posterior (dorsal) root of the spinal nerve carry these fiber
Afferent or Sensory fiber
Location of cell bodies of somatic afferent or sensory fiber are
Spinal or Dorsal Root Ganglia
Location of dorsal root ganglia
Intervertebral Foramina
These nerves unite to form spinal nerve
Dorsal root
Ventral root
Spinal nerve divide into
Ventral Rami
Dorsal Rami
These nerves supply the intrinic muscle of the back and overlying skin
Dorsal Rami
These nerves form the brachial plexus
Ventral Rami
These ventral rami form cervical plexus
C 1-
These ventral rami form brachial plexus
C 5-8
T 1
These ventral rami form Lumbar plexus
L 1
L 4
These ventral rami form sacral plexus
L 4-5
S 1-4
These ventral rami form coccygeal plexus
S 4-5
Co 1
These ventral rami do not form plexus
Thoracic nerve-( travel in intercostal space)
These ventral rami unite to form superior trunk of the brachial plexus
Ventral rami of 5th and 6th cervical nerve
This ventral rami remain single, and continue as middle trunk
Ventral rami of 7th cervical nerve
The inferior trunk or lower trunk of the brachial plexus are made out of
8th cervical nerve
1st Thoracic nerve
At this point each trunk split into anterior and posterior division
Above Clavicle
At this location the three posterior division unite to form posterior cord
Location of ventral rami and Trunk
In neck- Supraclavicular part of brachial plexus.
Above and behind middle third of clavicle
Location of cords of the brachial plexus
Axilla - infraclavicular
At this location brachial plexus divide into nerve
