P2- FITB & TF (Axilla ) Flashcards
axilla is
pyramidal shape located in the axillary region of the body
what structure axilla contains?
blood vessels
nerves
lymph nodes
The axillary arteryis a continuation of
a continuation of the subclavian artery and supplies blood to the upper limb.
The axillary vein drains blood from
the upper limb and is formed by the union of thecephalicandbasilic veins.
The brachial plexus is
network of nerves that supplies the upper limb and is formed by the anterior rami of spinal nerves C5-T1.
The axillary lymph nodes are grouped into
five clusters:
-pectoral
-subscapular
-lateral
-central
-andapical
The pectoral lymph nodes are located
along thepectoralis major muscle.
The subscapular lymph nodes are located
the subscapular vessels
The lateral lymph nodes are located
along the axillary vein
The central lymph nodes are located in
fatty tissue of axilla
Theapical lymph nodesare located at
at the apex of the axilla and drain into thesubclavian lymph trunk.
The axillary sheat his
is a fibrous sheath that encloses the axillary artery,vein,and brachial plexus.
The pectoralis major muscle forms
anterior wall of axilla
The latissimus dorsi muscle forms
part of the posterior wall of the axilla.
The serratus anterior muscle forms
part of the lateral wall of the axilla.
The subclavius muscle is
small muscle that lies beneath the clavicle and helps stabilize the shoulder joint.
The pectoralis minor muscle is
a thin,triangular muscle that lies beneath the pectoralis major and inserts on thecoracoid process.
The axillary artery is divided into
three parts by the pectoralis minor muscle.
The axillary vein lies
medial to the axillary artery and is formed by the union of the cephalic and basilic veins.
The brachial plexus passes through
the axilla and gives off several branches,including themusculocutaneous, median, radial, and ulnar nerves.
The axillary lymph nodes play a crucial role in
filtering lymph from the upper limb and breast.
The axillary sheath extends from
from the clavicle to the teres major muscle.
Theaxillary artery gives off several branches including
the superior thoracic artery,
thoracoacromial artery,
circumflex humeral arteries.
The axillary vein drains into
the subclavian vein,which then joins theinternal jugular vein to form thebrachiocephalic vein.
The axilla is an important anatomical region for
surgical procedures,such asaxillary lymph node dissectionandbreast cancer treatment.
The axillary artery is a continuation of the brachial artery.
FALSE
It is a continuation of the subclavian artery.
The axillary vein drains blood from the upper limb and drains into the subclavian vein.
TRUE
The brachial plexus is formed by the anterior rami of spinal nerves C5-T1.
TRUE
The axillary lymph nodes are grouped into five clusters:pectoral,subscapular,lateral,central,and apical.
TRUE
The axillary sheath encloses the axillary artery,vein,and brachial plexus.
TRUE
The pectoralis major muscle forms the posterior wall of the axilla.
FALSE
it forms anterior wall
The latissimus dorsi muscle forms part of the anterior wall of the axilla.
FALSE
It forms part of the posterior wall.
The axillary artery is divided into three parts by the pectoralis minor muscle.
TRUE
The axillary vein lies lateral to the axillary artery.
FALSE
it lies medial to the axillary artery
The pectoralis minor muscle inserts on the humerus.
FALSE
it insert on the coracoid process
The brachial plexus gives off the musculocutaneous,median,radial,and ulnar nerves.
TRUE
The axillary lymph nodes play a crucial role in filtering lymph from the upper limb and breast.
TRUE
The axillary sheath extends from the clavicle to the teres major muscle.
TRUE

FALSE
it drains into subclavian vein
The axilla is an important region for surgical procedures like axillary lymph node dissection.
TRUE
