Physiology Exam 8 (EEOB 2520 OSU
Spring 18) Questions and All Accurate
Answers.
Somatosensory nervous system (Afferent) - Answer Skin
joints
muscles
bones
tendons
What does Somatosensory nervous system detect? - Answer Touch
Proprioception (Body Position; where your body parts are without looking at them)
What receptor design does the somatosensory nervous system use? - Answer Afferent only
(ONLY ONE THAT USES THIS THAT WE WILL TALK ABOUT)
Why does the somatosensory nervous system use this receptor design? - Answer More
speed (lose adequacy)
Why do we need speed in the somatosensory nervous system? - Answer to know if
something is touching us (rumbling steering wheel example)
What categories of receptors do we have for the somatosensory nervous system - Answer
Thermoreceptors
Mechanoreceptors
Nociceptors
(TMN= Too Many Nuggets)
, Somatosensory Cortex - Answer Spatially-based position in brain (cortex of cerebrum; can
see body parts in pattern)
Homunculus means - Answer Little man (bigger parts means theres more sensory
information there)
if we change how much our brain is devoted to a certain area, would this affect other areas? -
Answer yes (acclimatization; one area grows, other place shrinks. this is because of limited
space)
Sensory nervous system (Visual) - Answer Electromagnetic Waves (photons; we can detect
this)
Visual Receptors? - Answer Photoreceptors
Components of Sensory nervous system (Visual) - Answer Cornea
Lens
Retina
Cornea and lens function - Answer Focus (focus energy to hit back of our eye which is the
retina)
Retina function - Answer Registers light (transforms energy)
In the retina, are the afferent neurons in the front or the back? - Answer Front
In the retina, are the receptors in the front or the back? - Answer Back
Why are our eye designed bad? - Answer Cells absorb the energy (alot of energy is lost;
reason its hard to see at night)
Pathway for energy coming into eye - Answer Cornea
Lens
