Q

What is sensory input?

A

sensory receptors monitor changes occurring both inside and outside the body. These changes are called stimuli.

Q

Describe the hypothalamus

A

involved in motivation and regulation and the intergration of many metabolic and autonomic processes.

Controls body temp, hunger, thirst, and circadian cycles and links the nervous and endocrine systems

Q

Describe the spinal cord

A

concerned with reflex actions involving the body below the neck, conducting sensory impulses from skin and muscles to the brain and carries motor impulses from the brain to muscles below the neck

Q

what are mixed nerves?

A

provide a 2 way communication system between the zonal cord and parts of the arms, legs, neck and trunk of the body

17
Q

how many cervical nerves are there?

A

8 pairs C1-C8

18
Q

how many thoratic nerves are there?

A

12 pairs T1- T12

19
Q

how many lumbar nerves are there?

A

5 pairs L1-L5

20
Q

how many sacral nerves are there?

A

5 pairs S1-S5

21
Q

How many coccygeal nerves are there?

A

1 pair

22
Q

Describe a neuron?

A

consist of a cell body and dendrites (extensions) and an axon or nerve fibre, which carries information from the cell body to or from the CNS

23
Q

What are further characteristics of a neuron?

A

extremely long lived but cannot undergo mitosis and divide

high metabolic rate needing continuous glucose and oxygen

24
Q

What to sensory nerves/ neurons do?

A

carry stimuli from peripheral areas to the zonal cord and downwards to the brain

25
Q

What do motor nerves are neurons do?

A

carry stimuli from the spinal cord to striated muscles to initiate contraction

26
Q

what are somatic sensory fibres?

A

sensory fibres delivering impulses from the skin, skeletal muscles, and joints

27
Q

What are the nerves from the internal organs called?

A

visceral sensory fibres

28
Q

What does the PNS do?

A

it keeps the CNS informed of events going on in and outside of the body

29
Q

What is the characteristic of the sympathetic division?

A

the system as a whole is usually stimulated

fear, flight or fight

30
Q

Example of the sympathetic nervous system

A

eye: dilation of the pupil
lungs: dilation of bronchioles
bladder: increased muscle tone
uterus: contraction in pregnant women, relaxation in non pregnant women

31
Q

What is the characteristic of the parasympathetic division

A

limited parts of he system are stimulated

resting and digesting

32
Q

Examples of the parasympathetic division?

A

eye: constriction of pupil
lungs: constriction of bronchioles
bladder: increased contraction

33
Q

What are the adaptations to the nervous system in pregnancy>

A

pregnancy hormones do affect the CNS but it is not well understood

these things happen due to the altered output of the endocrine system:
musculo-skeletal discomforts
sleep disturbances
alterations in sensation
