BIOS 252 Exam 3
Free Nerve Endings - ANSpain, temperature changes, tickle and itch
Encapsulates Nerve Endings - ANStouch, pressure, vibration
Special Sensory Cells - ANSused to create special sensory reception
Tactile Free Nerve Endings - ANSitch, tickle
Non-Tactile Free Nerve Endings - ANStemperature changes, pain
Meissner's Corpuscle - ANSlight touch, low frequency vibration
Type I Cutaneous Mechanoreceptor: Merkel Cells - ANSpressure
Type II Cutaneous Mechanoreceptor: Ruffini's Corpuscle - ANSlight and deep pressure
(baroreceptors)
Lamellated Corpuscles: Pacinian Corpuscle - ANSvibration
Fibrous Tunic of the eye - ANSsclera and cornea
Sclera - ANSwhite of the eye; where extrinsic eye muscles attach
Cornea - ANSthe transparent outer covering of the eye that allows light to pass through
Vascular Tunic - ANSchoroid, ciliary body, iris
Choroid - ANSmiddle, vascular layer of the eye, between the retina and the sclera. center of the
optic nerve made of connective tissue and blood vessels
Ciliary Body - ANSring of tissue behind the peripheral iris that is composed of ciliary muscle and
ciliary processes
Ciliary Process - ANSproduces aqueous humor
Zonular Fibers - ANSconnect the lens to the ciliary body
Retina - ANSA light-sensitive layer of the eye; contains rods and cones, bipolar cell layer,
ganglion cell layer, horizontal cell layer, and amacrine cells.
