Question 1

Reflex Pathway

Answer 1

• an organization of neurons that enable the body to react quickly
• can be simple or complex

Question 2

Pathway depends on 3 overlapping functions

Answer 2

• sensory input
• Intergration
• Motor Output

Question 3

Sensory Input

Answer 3

info coming in from 5 senses

Question 4

Intergration

Answer 4

-Combining 2 things to become a whole

Question 5

Motor Output

Question 8

Sensory Neuron

Answer 8

Question 9

Interneurons - Intergration Center

Answer 9

• connects sensory neurons & motor neurons

- located in spinal cord

Question 10

Motor Neuron

Answer 10

-carries info away from Cns towards effectors

Question 11

Effector

Answer 11

• muscle or gland

- effector has an effect

Question 12

Response

Answer 12

• muscles will contract

- glands will secrete

Question 13

Reflex Arc

Answer 13

• A simple connection of neurons that start with a stimulus & ends with a response
• response is automatic
• response is controlled through spinal cord without direct involvement of brain
• do not feel pain until after withdrawal
