Quiz 3

Phasic

This type of receptor quickly adapts and will return to its resting potential even if a stimulus is still being applied.

Mechanoreceptors

This type of receptor detects deep touch (skin) and vibrations (ear).

Visceral reflex

In a reflex, if an effector is a gland, this is called a/an _______

Chemoreceptors

Gustation uses this type of receptor.

Polysynaptic

This reflex pathway uses interneurons.

Reffered pain

This perception of visceral pain as somatic pain in one area of the body when the issue is located somewhere else is called ______ pain perception.

Punctate

This refers to the pattern of uneven distribution of sense organs.

Excitability

This property of neurons that allows them to respond to stimuli.

Relative

When you placed your hands in the room temperature bath, but felt two different sensations, this showed that thermoception __________

proprioceptor

The type of receptor activated by the Taylor's hammer in last week's lab.

Two-point

This test used a caliper to evaluate the density of touch receptors in a specific region of the skin.

Monosynaptic

A reflex pathway that involves only one synapse and one interneuron

Baroreceptors

detect pressure changes like blood pressure against artery walls

thermoreceptors

Temperature sensors in the body that detect heat or cold.

Somatic reflex

An involuntary response involving skeletal muscles.

hyporeflexic

Having weaker or reduced reflexes than normal.

Hyperreflexic

Having exaggerated or overactive reflexes.

Nociceptors

pain receptors that respond to harmful stimuli like extreme heat, pressure, or chemical damage. detects pain.

Tonic receptors

Continue to fire when stimulated. Adapts slowly.

Absolute

The brief period after a nerve fires during which it cannot fire again, no matter how strong the stimulus is

Punctate distribution

unequal distribution of receptor densities in the skin.

Receptor

Specialized to respond to stimulation

Afferent (sensory neuron)

PNS signals headed toward the spinal cord (CNS)

Integrations in the CNS

function of interneurons in spinal cord (CNS) if involved in response.

Efferent (motor) neuron

PNS signals leaving the spinal cord (CNS)

Effector (gland, organ, muscle, etc)

Tissue that makes a response

The Babinski response should be negative in adults

True

There are more cold than warm receptors in the integument.

True
