Document Summary

Sensory, motor & integrative systems: sensory & motor pathways of body provide routes for input into brain & spinal cord and for output to targeted organs for responses (e. g. muscle contraction) Somatic senses includes tactile sensations (touch, pressure, vibration, itchy & tickle), thermal sensations (warm & cold), pain sensations & proprioceptive sensations. Proprioceptive sensations allow perception of both static (nonmoving) positions of limbs & body parts (joint/muscle position sense), and movements of limbs/head. Visceral senses provides info about conditions within internal organs (e. g. pressure, stretch, chemicals, nausea, hunger, temperature) (2) special senses sensory modalities of smell, taste, vision, hearing & equilibrium/balance. Different types of sensory receptors involved in different senses. Sensory receptors grouped based on structural & functional characteristics (1) microscopic structure (2) location of receptors and origin of stimuli that activate them (3) type of stimulus detected. Sensory receptors respond to stimuli by generating receptor potentials (1) free nerve endings/nonencapsulated (of first-order sensory neuron)
