Nervous and Endocrine Systems

CNS & PNS

100

What structures make up the CNS?

Brain and spinal cord

200

The peripheral nervous system is...

All of the nerves outside of the CNS

300

Describe one difference between the CNS and PNS

Any difference

400

Describe one similarity between the CNS and PNS

Any similarity

500

The name of the chemical messenger that carries nerve impulse messages from one neuron to another. 

Neurotransmitters

Neurons

100

Part of the neuron that receives nerve impluses (messages)

Dendrites

200

Name the 3 types of neurons

motor, sensory, interneurons

300

Part of the neuron that surrounds the axon

Myelin sheath

400

Where do sensory neurons receive information from?

Sense receptors in the body

500

Describe the process of a nerve impluse travelling from one neuron to another. 

axon terminals release neurotransmitters.

neurotransmitters travel across synapse to next neuron

Dendrites of next neuron receive the nerve impulse message

Brain

100

The name of the lobe at the front of the brain

Frontal lobe

200

The name of the lobe at the back of the brain

Occipital lobe

300

Name all four lobes of the brain

Frontal, parietal, temporal, occipital

400

Where is the brain stem located and what does it become?

Base of the brain, becomes the spinal cord

500

Choose one lobe of the brain and describe its function

Function of any of the 4 lobes

Endocrine System

100

What is the endocrine system?

All of the glands within the body that produce and secrete hormones

200

True of False? The speed of a message is slower in the endocrine system than the nervous system.

True

300

Once a hormone is released from a gland, what does it travel through in the body?

Bloodstream

400

Define "negative feedback reaction"

regulatory loop in which the body responds in the  opposite direction to a stimulus to maintain homeostasis.

500

Name one hormone, its production site, target cell and effect on the body.

Any hormone from endocrine system

Reflexes

100

Define reflex action.

Involuntary movement in response to a stimulus

200

True or False? An effector is most likely to receive a message from a motor neuron

True

300

Draw a flow diagram of the "stimulus-response model"

stimulus - receptor - control centre - effector - response

400

Between which two stages in the stimulus response model would you expect a sensory neuron to carry information

From receptor to control centre (CNS)

500

Explain how a reflex action is different to a nerve impulse reaction

reflex only travels to spinal cord then response, nerve impulse goes to the brain
