|
General senses
|
Simple neural pathaways that include touch, temperature, pain, chemical and pressure detection, and body position.
|
|
Special senses
|
Complex pathways housed in specialized organs that include gustation (taste), olfaction (smell), vision, audition (he.aring), and equilibrium
|
|
Receptive field
|
A sensory neuran that (sometimes wrapped in a sheath of connective tissue) monitors a specific region.
|
|
What is a labeled line?
|
A labled line is the connection where an neuron connects to a receptive field.
|
|
Sensory coding
|
Provides the central nervous system with such information as intensity, duration, variation, and movement of the stimulus.
|
|
Referred pain
|
A pain sensation projected to another part of the body other than the part that was originally affected
|
|
Tonic receptors
|
Always on to sense pain
|
|
Phasic receptors
|
Turned on by a stimulus (hair root plexuses, tactile corpuscles, and Pacinian corpuscals) all are phasic receptors for touch.
|
|
Proprioreceptors
|
Receptors for body position
|
|
Muscle spindle receptors
|
Inform the brain of muscle tension
|
|
Golgi tendon organs
|
In tendons near joints that tell the brain about koint position
|
|
Thermoreceptors
|
Sensors that detect changes in temperature. They cover a large portion of the body including the dermis, skeletal muscles, and the hypothalamus of the brain ( our internal thermostat)
|
|
Baroreceptors
|
Ocnvey signals about liquid and gas pressure (usually the tips of sensory neuron dendrites in in blodd vessels and the lungs)
|
|
Free nerve endings
|
The branch that the dendrite sits at the end of
|
|
Chemoreceptors
|
Monitors changes of various bodily chemicals
|
