Unit 10 Sensory Systems

Question 1

Name 3 sensory receptor types

Answer 1

• a neuron with free ending dendrites (pain and temperature)
• a neuron with an encapsulated ending (pressure and touch receptors)
• specialized receptor cell (light receptors)

Question 2

These 3 receptors are classified based on the location of the stimuli

Answer 2

Exteroreceptor - located near stimulus in the environment (located on the skin)

Interoreceptor - interrupt from internal organs and tissues (sense blood pressure)

Proprioreceptors - near a moving part of the body (receptors in the muscles)

Question 3

Name Functional Receptor Types

Answer 3

**respond to type of stimuli

chemoreceptors - detect chemical stimuli (taste, smell, pain, and solute)

Mechanoreceptor - interpret physical stimuli (press, vibration, sound, body position)

Thermoreceptor - sensitive to temperature changes

Photoreceptors - detect light

Question 4

What are the parts of the ear and their functions?

Answer 4

External ear - collects and focuses sounds waves

middle ear - transmits the sounds waves

inner ear - traduces the sounds waves into a neuronal signal

Question 5

What is the external ear composed of?

Answer 5

the auricle, auditory canal (ear canal), tympanic membrane

Question 6

What does the middle ear consist of?

Answer 6

mallues, incus, staples

tympanic cavity

Question 7

What are the is in the inner ear?

Answer 7

Vestubule, vestibular nerve, cochlea, cochlear nerve

round window, eustachian tube
