Nervous & Endocrine System

Front 1

main function of nervous system

Back 1

a network of neurons that controls all systems in your body

Front 2

function of endocrine system

Back 2

a chemical communication system that controls the internal environment of the body using hormones, glands and the circulatory system.

Front 3

similarities between the nervous and endocrine systems

Back 3

these two systems are responsible for sending messages to signal cells

Front 4

differences between the nervous and endocrine systems

Back 4

1. endocrine system moves slowly whereas the nervous system is very fast

2. endocrine system moves through the circulatory system where as the nervous system has its own network

3. endocrine system sends hormonal (chemical) messages whereas the nervous system uses electrical impulses which are sent through neurotransmitters

Front 5

how messages are sent in the nervous system

Back 5

the nervous system sends messages around the body via neurons of nerve cells. these messages are electrical and travel at fast speeds

Front 6

how messages are sent via the endocrine system

Back 6

the endocrine system sends chemical messages around the body via the circulatory system. these messages are fairly slow compared to the messages sent via the neurons in the nervous system.

Front 7

function of hormones

Back 7

hormones are chemical substances that act as messengers in the body. they regulate water balance, glucose levels, body temperature and the body’s growth

Front 8

production of hormones

Back 8

there are multiple glands that are responsible for creating different hormones. each gland is responsible for different types of hormones but the main glands are pituitary gland (also known as the master gland) and the hypothalamus

Front 9

breakdown of central nervous system

Back 9

receives, responds and transmits messages to and from the PNS. it includes the brain and the spinal cord.

Front 10

breakdown of peripheral nervous system

Back 10

carries the messages to and from the CNS to the different systems and parts of the body

Front 11

how messengers are sent along neurons

Back 11

messages in the nervous system are moved by using trillions of cells called neurons to move around the body. they pass messages onto each other until it reaches its destination. the dendrite receives the electrical message from the previous cell, then the message passes through the cell body into the axons which are then chemically transferred by neurotransmitters across the synapse.

Front 12

function of motor neuron

Back 12

motor neurons take neurons to the effectors (OMG - organs, muscles and glands)

Front 13

function of sensory neuron

Back 13

sensory neurons carry the impulse generated by the stimulus to the central nervous system

Front 14

function of interneurons

Back 14

interneurons carry the impulse through the central nervous system

Front 15

function of the parietal lobe

Back 15

1. knowing left from right

2. sensation

3. body orientation

4. spacial perception

Front 16

function of temporal lobe

Back 16

1. understanding language

2. behaviour

3. memory

4. hearing

5. categorising objects

Front 17

function of frontal lobe

Back 17

1. problem solving

2. emotions

3. reasoning (judgement)

4. speaking

5. motor activities

Front 18

function of occipital lobe

Back 18

1. vision

2. colour perception

3. visual interpretation

Front 19

function of cerebrum

Back 19

high order thinking

Front 20

function of corpus callosum

Back 20

allows messages to travel to the left hemisphere to the right hemisphere

Front 21

function of cerebellum

Back 21

receives information from sensory systems and parts of the brain. coordinates voluntary movements like balance, posture, coordination and speech

Front 22

function of medulla

Back 22

helps regulate breathing. heart and blood vessel function, digestion, sneezing and swallowing

Front 23

reflex actions and their pathway

Back 23

stimulus (what happens)

receptor (receives messages)

sensory neuron (moves the message)

interneuron (spinal cord)

motor neuron (sends the action)

effector (effect)

response (action)

Front 24

how reflex actions are different to most other responses

Back 24

reflexes work just like normal messages, however, they reach the spinal cord and return back (basically skipping the brain)
