The right ventricle pushes deoxygenated blood away from the heart via arteries into the lungs, within the lungs CO2 is removed and this is added

oxygen

structures that make up the ANTERIOR BOUNDARY of the axilla

pectoralis major and minor

the thoraco-acromial artery supplies blood to the

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

anterior rami

The left ventricle directly pumps blood into this large artery

aorta

a nerve network that supplies the muscles and skin o the upper limb

brachial plexus

The three large branches of the aorta that stem directly from the arch of the aorta to supply the head and upper extremities are

brachiocephalic trunk, left common carotid artery, left subclavian artery

this artery travels to the posterior side of the scapula to connect with the suprascapular and dorsal scapular arteries

circumflex scapular artery

structures that make up the INFERIOR BOUNDARY of the axilla

deep fascia extending between the arm and thorax

the anterior and posterior circumflex humeral arteries supplies blood to the

deltoid

the axillary nerves innervates (controls) the

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

in the inferior part of the neck, the roots from C7 continues as this trunk

middle trunk

What structures create the letter "M" over the axillary artery in the axilla

musculocutaneous nerve, lateral root of the median nerve, median nerve, medial root of the median nerve, and ulnar nerve

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
