nervous and endocrine system

Question 1

the nervous system is made up of

Answer 1

the brain and the spinal cord

Question 2

the peripheral system relays …

Answer 2

messages from the environment to the CNS via sensory neurones and from the CNS to effectors via motor neurones

Question 3

the PNS is further subdivided into the

Answer 3

autonomic nervous system and
somatic nervous system

Question 4

the autonomic nervous system is vital to the body as it

Answer 4

control involuntary function
such as maintaining heart rates and breathing rates

Question 5

the autonomic system is also divided into the

Answer 5

sympathetic and
parasympathetic nervous system

Question 6

the sympathetic and parasympathetic work as an antagonistic pair during

Answer 6

rest and digest response
- crucial in producing the physiological arousal to maintain fight/flight

Question 7

the endocrine system is the main chemical messenger of the body where hormones are

Answer 7

secreted into the blood stream from glands and transported towards target cells in the blood , with complementary receptors

Question 8

the pituitary gland is considered to be the master gland as it

Answer 8

controls the release of hormones from all other glands in the body

Question 9

the adrenal gland releases adrenaline which creates the physiological around preceding the

Answer 9

fight or flight response
through increasing the activity within the sympathetic branch of the nervous system

Question 10

fight or flight 1
the body senses and becomes aware of a

Answer 10

stressor in the environment ie a speeding car

Question 11

fight or flight 2
through sensory receptors and sensory neurones in the PNS this information is sent to the

Answer 11

hypothalamus in the brain which co ordinates a response and triggers increased levels of activity in the sympathetic branch of the ANS

Question 12

fight or flight 3
adrenaline is released from the adrenal medulla in the adrenal glands and is transported to

Answer 12

target effectors via the blood and through the action of the endocrine system

Question 13

fight or flight 4
this results in the rectum contracting , saliva production being inhibited and a greater breathing rate this creates the physiological response needed to sustain the

Answer 13

fight or flight reins , whose adaptive purpose is to enable us to escape the stressor and so increase the likelihood of our survival

Question 14

fight or flight 5
once the stressor is no longer a threat as a part of the antagonistic paring the hypothalamus triggers less activity in the sympathetic branch and more activity in the parasympathetic branch of the ANS this is also referred to as the

Answer 14

rest and digest response due to the parasympathetic branch decreasing the activity which was originally increased through the action of the sympathetic branch
