Q

What is the difference between the endocrine system and TNS

A

The main difference is that while the nervous system transmits information
via nerves, the endocrine system uses blood vessels to deliver hormones to
their target sites in the body.

Q

What is the Spinal Cord responsible for

A

Passing messages from the brain to the rest of the body (form of electrical impulses)
Transmitting messages back to the brain from various parts of the body

Q

What is the purpose of the somatic nervous system

Concious

A

Passing messages from sensory organs to the brain
Controls the body’s conscious actions (voluntary)
- Movement etc.

Q

What is the purpose of the autonomic NS

A

Controls the body’s automatic actions such as breathing
The functions happen quickly so we do not think about it
No conscious thought over the decision

Q

What is the role of the Parasympathetic System

Q

What physical factors takes place during the activation of the Para Sympathetic Nervous System

A

Decreased heart rate
Increase activity in stomach

16
Q

What is the role of the Peripheral NS

A

Connects the central nervous system (CNS) to the rest of the body
- Relays information via nerve impulses (an electrical impulse) from the rest of the body and back to the CNS

17
Q

What is the role of the peripheral nerves

Brain, Spinal Chord

A

Peripheral nerves pick up information about the body and send messages to the spinal cord
Brain sends out impulses to peripheral nerves to control our actions

18
Q

What is a neuron

A

Cells in the NS that carry impulses
- Different types of neurons do different things
- Connect brain and body with impulses

19
Q

What is synaptic transmission

A

Process that moves communicated messages around the body

20
Q

What are the 6 structures of a neuron

A

Cell Body
Dendrites
Axon
Neural Impulse
Myelin Sheath
Terminal Branches

21
Q

Define Cell Body

A

The Cell’s main source of support
In control of the system

22
Q

Role of Dendrites

A

Receive information from other neurons, called pre-synaptic neurons, or from the environment
Take them in as Neurotransmistteres

23
Q

Role of Axon

A

Carry electrical impulses within the brain and between the brain and the rest of the body

24
Q

Define Neural Impulse

A

An electrochemical signal that is sent from neurons to other neurons

25
Q

Define Myelin Sheath

A

Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord
Improves efficency of electrical impulses along nerve cells

26
Q

Define Terminal Branch

A

The terminal branches of an axon change electrical impulses or action potentials within a neuron into chemical messages in the form of neurotransmitters

27
Q

What are the 3 types of neurons

A

Sensory
Relay
Motor
