simple reflexes

Question 1

what is a neural reflex

Answer 1

stereotype involuntary raction of the CNS to specific sensory input

Question 2

what is the stereotype in terms of simple reflexes

Answer 2

it response in the same way every time (predictable response)

Question 3

what is the involuntary feature of neural reflex

Answer 3

reflex without conscious thought so rapid response

Question 4

what are the functions of reflexes

Answer 4

1. protective
   - stops us damaging ourselves
2. postural control
   - pattern of skeletal muscle movement
3. homeostasis
   - maintaining internal conditions (ANS)

Question 5

what is the chain of the reflex arc

Answer 5

sensory receptor -> afferent -> integration -> efferent -> effector

Question 6

where are interneurons found

Answer 6

1. in the CNS
2. in the enteric nervous system

Question 7

what is the role of interneurons in nerve responses

Answer 7

they work to combine a range of info, sort it and determine a response (can bring info outside the reflex arc as well)

Question 8

true or false the reflex arc communicates with other parts of the nervous system

Answer 8

true the reflex arc communicates with other parts of the nervous system

Question 9

true or false the brain cannot override a reflex arcs

Answer 9

the brain communications (conscious control) can stop reflex arcs

Question 10

what are the efferent neurones

Answer 10

motor neurone
which bring signals to effectors

Question 11

what is the role of simple strech reflex (myotatic)

Answer 11

• posture
• adjust the degree of muscle contraction

Question 12

what are the sensory receptors

Answer 12

proprioception

Question 13

what are the different types of reflexes

Answer 13

somatic
autonomic
combination of both
