Definition Flashcards
pansystolic murmur
through out the cardiac cycle
Mitral regurgitation
Myocytes
contain bundles of parallel myofibrils
each myofibril made up of sacromeres (basic unit of contraction)
sacromeres bound by two transverse Z lines
retrosternal heavy or gripping sensation with radiation to the left arm or neck that is provoked
by exertion and eased with rest or nitrates
angina
severe, tearing chest pain radiating through to the back
aortic dissection
sharp, central chest pain that is worse with movement or respiration but relieved with sitting
forward
pericarditis
myocardial ischaemia provoked by exertion on ECG
ST segment depression in leads facing the area
what nerve supplies the pericardium
phrenic nerve
axillary nerve innervates…
teres minor and deltoid muscles and dysfunction of this nerve usually presents with loss of movement or sensation to the shoulder area
accessory nerve innervation
muscles in the neck that attach to the shoulder (the sternocleidomastoid and trapezius muscles)
purely motor function to those muscles not sensory
Injuries involving the long thoracic nerve
associated with winging of the scapula, and are commonly caused by axillary surgery
what artery is the facial artery a branch of
external carotid
internal carotid artery supplies…
anterior and medial intracranial structures
vertebral artery
a branch of the subclavian artery and supplies the spinal cord, cerebellum and posterior intracranial structures
brachiocephalic artery
supplies the right side of the head and arm, this gives the subclavian and common carotid on the right-hand side
aortic dissection findings
false lumen of descending aorta
tearing chest pain
hypertension
aortic regurgitation (diastolic murmur over 2nd intercostal space right sternal border)
