pectoralis major and minor
What are the structures that make up the boundaries of the axilla
pectoralis major and minor, serratus anterior, subscapularis, humerus, and deep fascia extending between the arm and thorax
Period when the left and right ventricles contract
systole
The left ventricle pumps oxygenated blood throughout the body via
the aorta
in the inferior part of the neck, the roots of the brachial plexus merge to form
trunks
the medial cord generates the medial root of the median nerve and then continues as the (BLANK, nerve) into the anterior arm
ulnar nerve
These within the heart ensure that blood can only flow forward in the circuit. Meaning, that it prevents blood from flowing into the right atrium from the right ventricle during systole
valves
when each trunk passes under the clavicle and enters the axilla, each trunk will create a
anterior AND posterior division
after a short distance, the spinal nerves for two rami known as
anterior and posterior rami
this rami travels to the appendages and the anterolateral trunk

deltoid and teres minor
blood will flow from the right atrium into the right ventricle. And blood will flow from the left atrium into the left ventricle during this period when the heart is at rest
diastole
term given to when the heart is at rest
diastole
the lateral cord generates the lateral root of the median nerve, and then continues as the (BLANK, nerve) into the anterior arm
musculocutaneous nerve
the lateral cord is formed by the
merging of the anterior divisions of the superior and middle trunks

What nerves make of the branches of the brachial plexus
musculocutaneous nerve, median nerve, ulnar nerve, and radial nerve
what nerves enter the anterior arm
musculocutaneous nerve, ulnar nerve, and median nerve
the transverse cervical artery supplies oxygenated blood to the
trapezius
the brachial plexus is comprised of the anterior rami of the spinal levels
C5,C6,C7,C8, and T1
The right ventricle and atrium contain this type of blood. While the left ventricle and atrium contain this type of blood
Right - deoxygenated left - oxygenated
the anterior divisions of each trunk will supply these compartments of the arm AND forearm
anterior (flexor)
during systole, the right ventricles will push deoxygenated blood via
arteries
arteries carry blood
away from he heart
a pyramidal shaped passageway for nerves and blood vessels to travel between the neck and upper extremity
axilla
the lateral, medial, and posterior cord all reside within the
axilla
once the subclavian arteries pass the lateral edge of the first rib they are called
axillary arteries
the posterior cord generates the
axillary nerve
after the subclavian arteries leave the thorax via its superior opening, they then run over this bony process towards the axilla
first rib
A four chambered muscular pump that resides in the thorax
heart
These organs are protected by the vertebral thoracic column, ribs, and sternum
heart and lungs
structure that makes up the LATERAL BOUNDARY of the axilla
humerus
in the inferior part of the neck, the roots from C8 and T1 merge to form this trunk
inferior trunk
The anterior division of the inferior trunk continues as the
medial cord
the anterior divisions of the superior and middle trunk merge to form the
lateral cord
the medial cord is located (BLANK) to the axillary artery
medially
The lateral cord generates the lateral root of the
median nerve
the lateral cord is located (BLANK) to the axillary artery
laterally
the thoracodorsal artery supplies blood to the
latissimus dorsi
Oxygenated blood from the lungs is carried via the veins to this chamber of the heart
left atrium of the heart
the left subclavian artery supplies blood to the
left upper extremities
during systole, the right ventricles will push deoxygenated blood via arteries to go to
lungs
the posterior divisions of each trunk will supply these compartments of the arm AND forearm
posterior (extensor)
the posterior divisions of the superior, middle, and inferior trunk merge to form the
posterior cord
this rami travels to the muscles and the skin of the back
posterior rami
The posterior cord is located (BLANK) to the axillary artery
posteriorly
This nerve innervate the triceps brachii
radial nerve
the posterior cord generates the axillary nerve and then continues as the (BLANK, nerve) into the posterior arm
radial nerve
the dorsal scapular artery supplies oxygenated blood to the
rhomboids and levator scapulae
These organs also reside in the thorax and sit to the right and left of the heart respectively
right and left lung
The right and left subclavian arteries supply oxygenated blood to the
right and left upper upper extremities respectively
deoxygenated blood from throughout the body is carried to this chamber of the heart via large veins
right atrium
What are the four chambers of the heart
right atrium, right ventricle, left atrium, left ventricle
the brachiocephalic trunk separates into the
right common carotid artery and right subclavian artery
the right subclavian artery supplies blood to the
right upper extremities
The anterior rami of C5 - T1 are known as the (BLANK) of the brachial plexus
roots
Since the brachial plexus is made up of certain nerves, the plexus is thus made up of
roots, trunks, divisions, cords, and branches (R.T.D.C.B - Real Teachers Drink Cold Beer)
structure that makes up the MEDIAL BOUNDARY of the axilla
serratus anterior
the lateral thoracic artery supplies blood to the
serratus anterior
are created as merging anterior and posterior nerve roots exit the intervertebral foramen
spinal nerves
structure that makes up the POSTERIOR BOUNDARY of the axilla
subscapularis
the subscapular artery supplies blood to the
subscapularis and teres major
The subclavian arteries leave the thorax via its
superior aperture (opening)
in the inferior part of the neck, the roots from C5 and C6 merge to form this trunk
superior trunk
the suprascapular artery supplies oxygenated blood to the
supraspinatus and infraspinatus
during this period, the atrias will fully contract to ensure the ventricles are full prior to their contraction
the end of diastole
The right and left common carotid arteries supply oxygenated blood to
the head
what part of the vertebrae protects the heart and lungs
thoracic region
What bones protect the heart and lung
thoracic vertebral column, ribs, and sternum
The axillary artery generates numerous branches which includes the (4)
thoracic-acromial artery, lateral thoracic artery, anterior and posterior circumflex arteries, subscapular artery
the subscapular artery generate the branches
thoracodorsal artery and circumflex scapular artery
the subscapular artery generates these branches (2)
thoracodorsal artery and circumflex scapular artery
The left ventricle pumps oxygenated blood
throughout the body
oxygenated blood from the left ventricle will be pushed out through the aorta and the several branches of the aorta to supply
tissues of the rest of the body
in what direction do veins carry blood to
towards the heart
The subclavian artery generates numerous branches which includes the (3)
transverse cervical artery, dorsal scapular artery, suprascapular artery
