physiology

what are the jobs of the spinal cord

• connects the brain to the rest of the body, and controls reflexes

• transmitting taste signals

• Processing visual information

• Digesting food

What do the ventral roots do?

• Transmit sensory signals

• Process motor commands

• Process sensory signals

• sends signals out

What do the dorsal roots do?

• Transmit sensory signals

• Process motor commands

• Process sensory signals

• sensory info in

What is in the central canal?

• Sensory neurons

• Motor neurons

• Cerebrospinal fluid

• Blood vessels

What is in the white matter

• Cell bodies

• axons

• Dendrites

• Synaptic vesicles

What is a reflex?

• A voluntary action

• An involuntary response to a stimulus

• A type of neuron

• A type of brain wave

What does the receptor do?

• Initiates a reflex

• Transmits signals to the brain

• protects stimulus

• Causes a motor response

What does the sensory neuron do?

• Initiates a reflex

• Transmits signals to the brain

• brings messages from the receptor to the spinal cord.

• Causes a motor response

What does the motor neuron do?

• Initiates a reflex

• Transmits signals to the brain

• Detects stimuli

• brings commands to the effector

What does the effector do?

• Initiates a reflex

• Transmits signals to the brain

• Detects stimuli

• carries out the response
