Anatomy 1 Lab FINAL EXAM
** Covers exercises 13, 14, 15, 16, 17, 18, 20, 21, 22,
23, 24, 25, 26, 27**
Terms – Intro to Sensory Receptors (Lab 24)
General senses – touch, pressure, changes in temperature, pain, blood pressure and stretching
Special senses – taste, smell, sight, hearing, balance
Punctate distribution – uneven distribution of sense receptors
Stimuli are classified by type (modalities) such as light, heat, sound, pressure and specific chemicals
Receptors – receiving units in the body that respond to an adequate stimulus
Photoreceptors – detect light
Thermoreceptors – detect changes in temperature
Proprioreceptors – detect changes in the position of the body and in tension
Pain receptors (nociceptors) – naked nerve endings throughout much of body
Mechanoreceptors – receptive to mechanical stimuli (touch receptors or receptors in ear that respond to sound or motion)
Baroreceptors – respond to changes in blood pressure
Chemoreceptors – respond to changes in chemical environment
Tests – Intro to Sensory Receptors (Lab 24)
Mapping Fine-Touch Receptors – Meissner’s corpuscle and Merkel discs (use a hair to detect when partner can sense it)
Two-Point Discrimination Test – number of fine touch receptors per unit area in the skin – map the relative density of the receptors in the skin – determine minimum distance that your lab partner is able to recognize as two points
Mapping Temperature Receptors – determine relative number of receptors that are sensitive to warm/cool
Adaption to Touch – length of time it takes for receptors to adapt to stimulus Tonic receptors – continuously perceive stimulus Phasic receptors – perceive the stimulus initially and then adapt
Locating Stimulus with Proprioception – touch lab partner with marker and see if they can mark same spot with a different color marker OR close eyes and try to touch corner of eye with finger
Temperature Judgment – examine adaption of thermoreceptors to temperature and the
