Slicing up the Brain
Getting Oriented
Peripheral Nervous System
Spinal Cord
100
These are the two major parts of the CNS
What is the brain and the spinal cord?
100
Slicing the brain stem/spinal cord
What is a cross section?
100
These directions are inward and outward from the spine, respectively.
What are medial and lateral, respectively?
100
These type of nerves transmit info from the real world/sense/internal organs to brain or SC.
What are the afferent nerves?
100
____ matter is cell bodies, ______ matter is myelinated axons.
What is gray and white?
200
This fills up the entire CNS
What is cerebral spinal fluid?
200
A length wise cut of the brain.
What is saggital?
200
In the human brain and in animals, these are up and down, respectively.
What are dorsal and ventral, respectively?
200
These nerves transmit information from the brain to the skeletal muscles and smooth muscle in your internal environment?
What is efferent nerves?
200
Sensory afferent nerves synapse here.
What are the dorsal horns?
300
These are the four open spaces in the brain.
What is the lateral, third and fourth ventricles? (Bonus points if included cerebral aqueduct)
300
A cut of the brain parallel to the ground
What is horizontal or axial?
300
In the human brain and in animals, these are left and right respectively.
What are anterior and posterior, respectively?
300
This is the division of the PNS that interacts with the outside world
What is somatic nervous system?
300
These contain the motor efferents.
What are the ventral horns?
400
Tightly packed cells that protect the the brain from harmful substances.
What is the blood-brain barrier?
400
This is a cut directly between the two hemispheres.
What is mid-saggital?
400
In the human body, these directions are up and down.
What are anterior and posterior, respectively?
400
This is the division of the autonomic nervous system that gives the "fight or flight" response.
What is the sympathetic nervous system?
400
The areas of the body that input sensory information and receive motor signals from a given section of the spinal cord.
What are the dermatomes?
500
The three protective membranes under the bone
What re the meninges, specifically the pia mater, arachnoid layer and dura mater?
500
This cut of the brain has the same orientation as looking at another face-to-face.
What is frontal/coronal?
500
In the human body, these are the directions that face the back and the stomach, respectively.
What are dorsal and ventral, respectively.
500
This is the division of the ANS that "rests and digests."
What is the parasympathetic nervous system?
500
This is the number of pairs of nerves attached to the spinal cord
What is 31?
