nervous system and cardio Flashcards
condensation of
elastic fibers
Internal elastic membrane
Large vessels have
—
(nerve and blood supply of the vessels) occur within tunica media
nervi and vasa vasorum
least common and most permeable; incomplete basement membrane; present in liver, spleen, bone marrow
Sinusoid
branch of arteriole with discontinuous layer of smooth muscle fibers surrounding it;
Metarteriole
has 1 layer of smooth muscle, lumen is abt the size of an RBC
Precapillary or terminal arteriole
equivalent to t. media, consists of
cardiac muscles, c.t. fibers, nerve and blood
vessels
Myocardium
Largest elastic artery in the body
aorta
no sharp line of demarcation between arterioles and small arteries
Artery
thin, web-like c.t. layer
Tela choroidea
forming H or butterfly shape consisting of nerve cell bodies, neuroglia, unmyelnted fibers & some myelinated
Gray matter
area in the white matter that occupies the region betwn DC,
dorsal funiculus
are accumulations of nerve cell bodies outside the CNS;
Ganglia
are the neuronal processes or nerve fibers connecting the brain, brain stem and spinal cord to peripheral dendritic zones or axon telodendria.
Nerve trunks
found in the hairless skin of the sole and palms which are pressure receptor
Meissner’s corpuscle
smaller version of pacinian found in the tongues and beaks of birds
Herbst corpuscles
