SCI - NERVOUS SYSTEM

What is the nervous system?

The nervous system is the body's main system for control and communication.

What does the nervous system consist of? (The two parts of nervous system)

• Central nervous system

• Peripheral nervous system

Fill in the blanks (Nervous system)

What is the brain? And is it part of which nervous system?

Command centre of the nervous system.
is part of central nervous system.

Where is the brain located?

Located in the Skull.

What is the brain made up of (In terms of the nervous system)

Neurons

What are nureons?

Nureons carry signals and messages throughout the body

What are neurons primarily used for?

They are responsible for processing information and sending messages/carrying signals

What are the parts of a brain?

• Cerebum

• Cerebellum

• Forebrain

• Mid brain

• Hindbrain

• Medulla Oblonga

Cerebum (where is it located and what does it control?)

Largest part of the brain. (Part of forebrain)

Used for thinking,problem solving and movement control

Cerebum left hemishere? (What does it control and do?)

Controls the right side of the body.

Movement,senses

Math calculations, problem solving

Logical reasoning

Cerebum Right hemisphere (What does it control and do?)

Controls left side of body.

Spatial reasoning and navigation

Cerebellum (where is it located and what does it control?)

Located at the back of the brain.

Controls balance and coordination.

Forebrain (where is it located and what does it control?)

Located in front

• Processes information

• Regulates emotions

• Controlling movements

Mid brain (where is it located and what does it control?)

Located in the middle

• Reflexes and Eye movements
  

Hindbrain (where is it located and what does it control?)

Located at the back of brain

Subconscious functions (Heartbeat, Breathing)

Medulla Oblonga (where is it located and what does it control?)

Base that connects the brain to the spinal chord

Fill in the blanks (REGIONS OF THE BRAIN)

What is the spinal chord?

Network of nerves that carries impulses from the body to the brain

What is the role of the spine in the spinal chord?

The spine protects the spinal chord allowing messages/signals to pass through

What are nerves?

They act as pathways of information, carrying messages/signals from the brain and body

What do neurons do?

Transmitting messages/signals throughout the body

What are the 3 main parts of neurons?

• Cell body

• Dendrites

• Axon

What is the cell body in neurons?

Nucleus and other components (organelles) in cell body

What are dendrites in neurons?

Receive information from other neurons

What is the axon in neurons?

Sends information to other neurons

Fill in the blanks (Neuron/Nerve cell)

What are the types of nurons?

• Sensory

• Motar

• Internuron

Sensory nuron

Receptor/recives impulses
