NLN PAX-RN Human Anatomy and
Physiology Senses
Games and activities
Chemical receptors - -Found in nasal passage and tongue receive stimuli
from environment and are associated with sense of smell and taste.
- Cochlea - -Part of inner ear that transduces/coverts the movement into
signals or action potentials.
- Cone cells - -Distinguish color in day.
- Cornea - -Transparent part of eye that allows light to enter the eye.
- Ear - -Responsible for hearing and balance. Divided into three regions:
Inner, outer and middle ear.
- Eustachian tube - -Connects to pharynx and equalizes pressure
between middle ear and atmosphere.
- Inner ear - -Has channels that contain fluid that moves in response to
your movement or sound.
- Iris - -Lyes behind cornea. Give eye color and regulates entering the
pupil.
- Lens - -Focuses light onto the retina. Shape is changed by attached
muscles.
- Middle ear - -Contains three small bones (ossicles):
Malleus
Incus
Stapes
Transmit vibration to oval window.
- Optic nerve - -Transmit information to brain when photoreceptor cells
are stimulated by light.
- Outer ear - -Collects sound and transmits to tympanic membrane.
- Pupil - -Located in center of iris. Light enters here.
- Retina - -Innermost layer of eye containing two types of photoreceptor
cells.
- Rod cells - -Sensitive to light. Distinguish black and white. Night vision.
