What are free standing structural nerves?
Bare dendrites of sensory receptors that convey to the brain the general sensations of pain, temps, tickle, itch and some touch sensations.
skin and skeletal
What are encapsulated structural nerve endings?
Encapsulated dendrite of sensory receptors that are enclosed in ct tissue capsule that convey the general sensations of pressure, vibration,and some touch sensations to the brain.
What are separate structural cells (more complex)?
sensory receptors of special sense are receptor cells that form synapses with sensory neurons.
(eyes, inner ear,nose and taste buds)
What are exteroceptor?
on the surface of the skin, provides external environment information
What are interoceptors?
inside the body, provides internal environment info
What are proprioceptors?
provide information about the position of muscle, tendons, joints, and inner ear.
what are the 6 types of stimuli that can be detected? c.o.m.p.t.n
What is a mechanoreceptors stimuli?
detect mechanical stimuli such as: sensations of touch, pressure, vibrations, hearing, and equallibrium. Also monitors the stretching of blood vessels and internal organs.
What is thermoreceptors stimuli?
detect changes in the temperatures (free ending neurons and exteroceptors)
What is photoreceptor stimuli?
detects light that strikes the retina
What is nocireceptors stimuli?
Respond to painful stimuli resulting from physical or chemical damage (free ending and exteroceptors)
What is chemoreceptors stimuli?
Detect the chemicals in the mouth, nose, and body fluids
What is osmoreceptors stimuli?
sense osmotic pressure of body fluids
what is referred pain?
pain that detected in another region of the body, other than the original organ.
what are the 3 classifications of referred pain?
- Superficial somatic pain
- Deep pain
- visceral pain
Describe superficial pain
pain that arises from the skin (sharp pain)
Describe deep pain
pain that arises from the muscles, joints, and tendons (dull throbbing pain)
Describe visceral pain
stimulation of nocireceptors in visceral organs (not localized, just a bad feeling)
