anatomy Flashcards
origin of phrenic nerve
C3,4,5
features of phrenic nerve
travel with JVP, supplies pericardium, leave through diaphragm
path of right phrenic nerve
anterior to right vagus, lateral to superior vena cava
right of pericardium
passes to right atrium to exit diaphragm at T8
path of left phrenic nerve
pass lateral to left subclavian artery, aortic arch, left ventricle
pass anterior to root of lungs
pierce through diaphragm
function of vagus nerve
provides parasympathetic supply to organs of the thorax and abdomen
sensory and motor features
vertebral position of larynx
C3-C6
nerve supply for diagram
C3,4,5
which valve only has 2 cusps while all the others have 3
mitral valve
define vital capacity
maximum volume of air that can be expire after maximal inspiration
where does vena cava perforate diaphragm
T8
where does oesophagus perforate diaphragm
T10
layers of the blood vessels inner to outer
endothelium
tunica intima
tunica media
tunica externa
where does aorta perforate diaphragm
T12: aortic hiatus
which 2 main artery branches supply the large intestines
superior mesenteric: ascending and transverse
inferior mesenteric: descending, sigmoid, upper rectal
branches of the superior mesenteric artery (caecum-> transverse)
ileocecal (caecum)-> right colic (ascending)-> middle colic (transverse)
branches of the inferior mesenteric artery (end of transverse-> rectum)
left colic-> sigmoid-> superior rectal
bones of appendicular skeleton
clavicle, scapula, pelvis
limbs
bones of axial skeleton
skull, ribs, vertebral coloumn
auscultation site for middle right lobe
between ribs 4-6 at mid-clavicular, mid-axillary line
auscultation site for lung base
posteriorly at scapular line at T11 vertebral level
position of horizontal fissure of the right lung
level of rib 4
position of oblique fissure of left and right lungs
anteriorly at rib 6 and rise to T3 posteriorly
where is anterior intercostal arteries branched from
anterior intercostal< internal thoracic< subclavian< brachiocephalic< aorta
where is anterior intercostal veins drained to
anterior intercostal> internal thoracic>right brachiocephalic> SVC
where is posterior intercostal arteries branched from
posterior intercostal< thoracic aorta < aortic arch
where does posterior intercostal veins drain to
posterior intercostal> azygous vein > SVC
order of the intercostal neuromuscular bundles (branches to the ribs)
veins
arteries
nerves
order of nerve name changes from vertebrae out
- dorsal rootlets->dorsal root-> dorsal root ganglion-> spinal nerve-> dorsal ramus (sensory/ posterior)
- ventral rootlets->ventral root-> spinal nerve-> ventral ramus (motor/ anterior )
larynx parts from top to bottom
eploglottis hyoid bone thyroid cartilage circothyroid ligament circoid cartilage trachea
cranial nerves for parasympathetic supply
oculomotor
facial
glossopharyngeal
vagus nerves.
only cranial sensimotor neurones not a part of parasympathetic supply
trigminal (5)
