1

What is innate and acquired reflex ?

Innate is natural like blinking when scared and acquired is when you learn like reading

2

Conditioned reflex ?

Is automatic reflex like driving on auto pilot

3

What neurotransmitter is associated with skeletal muscle ?

Acetylcholine

4

What are each receptors for ?
Mechanareceptor
Thermoreceptor
Photoreceptor
Chemoreceptors
Nociceptor

1- responds to force such as touch pressure vibrations
2- responds to temp change
3- eye respond to light
4- chemical change
5- pain extreme

5

Importance of Pupillary light reflex ?

Shows neurons are working

6

Patellar reflex

The tap on the knee

7

Define plantar and babinski reflex

Plantar - toes curl when foot ticketed
Babinski - big toe stands up when foot ticketed this could mean nerouns are damaged

Analgesia

Reduced ability to feel pain

16

Dermatomal maps are important clinically because

Locate nerve damage

17

Reflex arcs

Are Capel of receiving a stimulus and yielding a response

18

The large onion shaped receptors that are found deep in the dermis and subcutaneous tissue and that reaping to deep pressure are

Lamellar corpuscles

19

The peripheral nervous system includes

All neural structures outside the brain and spinal cord
