Flashcards for Chapter 16 Lecture Notes

Receptive field

The nerve ending that's receiving a certain place

Adaptation

Your body's ability to decrease sensitivity to a continuous stimulus.

General senses

Receptors that are usually tactile and proprioceptors of joints and chemical receptors.

General senses

The somatic and visceral receptors.

Somatic

Consciously controlled.

Visceral

Relating to the organs.

Tactile

Means touch

Proprioception

Your body's ability to tell where it is itself in space.

Exteroreceptors

Special sense receptor for external environment

Interoreceptors

Receptors for internal organs

Proprioceptors

Receptors that tell you where your limbs are in space.

Thermoreceptors

Receptors that respond to changes in temperature.

Nociceptors

Receptors that respond to pain caused by external and internal stimuli.

Baroreceptors

Receptors that detect changes in pressure within the body caused by stretch or distension.

Photoreceptors

Receptors that detect changes in color, intensity, and movement of light.

Referred pain

An inaccurate localization of sensory signals.

Tract

A pathway.

Decussate

Crossover from left to right.

Iris

A muscle that contracts and relaxes, which makes the hole, which is the pupil bigger or smaller.

Sclera

The white of your eye.

Choroid

Where all your veins and arteries are located in the eye.

Retina

Where all your rods and bones are gonna be that receive light information.

Astigmatism

A condition where your eye starts to lose its round shape, become a little more football shaped, and distort the image that you're seeing by skewing it.

Presbyopia

As middle aged persons get older, the lenses of their eye are no longer round because their ligaments slacken.

Rods and cones

Photoreceptors in your eyes.

Rods

These photoreceptors tend to be sensitive to light but only see in black and white.

Cones

These photoreceptors can see color and they can see detail.

Optic chiasm

The crossing of your brain in the eyes.

Stereoscopic vision

Depth perception.

Frequency

Measured in hertz, and that gives you the pitch.

Loudness

Measured in decibels.
