This type of receptor is sensative to stretching, compression, or twisting (causes disortions in receptor cell membrane to open ion channels)
This type of receptor provides sensation of touch, pressure, and vibration. Composed of free nerve endings between epidermal cells (sensative to touch/pressure), and root hair plexus (sensative to distortion/movement across body surface)
Tactile receptors have specialized sensory complexes. ________ is sensative to fine touch and pressure. Sensory neuron dendrites make contact with cells. Compression of these cells stimulate sensory neuorn dendrites.
Tactile receptors have specialized sensory complexes. ________ is sensative to fine touch, pressure and low frequency vibreations
Tactile receptors have specialized sensory complexes. ________ is sensative to deep pressure and pulsing/high frequency vibrations
Tactile receptors have specialized sensory complexes. ________ is sensative to pressure and disortions of skin.
This type of receptor monitors changes in pressure for the autonomic nervous system. Composed of free nerve endings that branch into blood vessels and the respiratory, digestive and urinary tracts. Stretching of the walls of these structures stimulate the dendrite and alter AP generation. Rapidly adapting to pressure changes
This type of receptor monitors positions in joints, tension in tendons and ligaments, state of muscular contraction. Located in joint capsules as free nerve endings, between skeletal muscles and tendons as the golgi tendon organs, and in the skeletal muscle as muscle spindles. Does not adapt, always sends info to CNS (so you know limb location at all times)
This type of receptor is sensative to only dissolved water soluble and lipid soluble substances. Adapts in a few secdonds, controls respiratory and cardiovascular functions inside the body, respiratory center in brain contain neurons that respons to pH, [H+ion], chemoreceptors located in carotid and aortic bodies monitor pH and [CO2/O2] or artrial blood
Their are 5 ______ senses, each responding to a specific stimulus. They are: smell (olfaction), taste (gustation), hearing (audition), equilibrium, and vision
Olfactory organs in the _____ cavity consist of: olfactory epithelium which contains: olfactory receptor cells, supporting cells, and basal cells
The _____ glands produce mucus covering the olfactory epithelium. The mucus prevents backup of stiumli, keeps area moist, and keeps area free of dust/debris
At the basal end of the olfactory receptor cell, cilia extend into the mucus. Water/lipid soluble substances dissolve in mucus and diffuse into cilia. _____ molecules bind to odorant binding proteins on cilia (binding causes a change in permeability and AP generation in the olfactory receptor cell
_____ receptors distributed over tongue surface and parts of the pharynx and larynx (most important on the tongue).
Taste buds contain taste receptors cells (_____ cells) and support cells. Buds are located on papillae- provides mechanical protection
Taste hairs/ ______ extend from gustatory cell into taste pore to detect dissolved chemicals.
Their are 4 primary taste sensations: sweet, salty, sour, bitter. Another additional taste is: _____- characteristic of beef/chicken broth and parmesan cheese
Their are 4 primary taste sensations: sweet, salty, sour, bitter. Another additional taste is: _____- no flavor, but mouth has ___ receptors in pharynx
