100
This is what is included in the CNS.
What are the brain and spinal cord.
100
These are the three meninges from superficial to deep.
What are: Dura mater, Arachnoid Mater, Pia mater
100
This is the part of the CNS contained in the cranial cavity.
What is the brain.
100
These receptors sense: compression, bending, stretching of cells. Touch, pressure, proprioception, hearing, and balance
What is mechanoreceptors
200
This produces the myelin sheath in the PNS.
What are Schwann Cells
200
This reflex utilizes muscle spindles.
What is the stretch reflex.
200
These are the three regions of the brainstem.
What is Medulla oblongata, Pons, Midbrain
200
These structures are deep in the dermis and sense deep pressure and vibrations
What is Pacinian corpuscles
300
This causes the contraction of the opposite extensor during Withdrawal Reflex.
What is the crossed extensor reflex.
300
These are the functions of the substantia nigra
What is reward, addiction, and movement.
300
This is the reason that there is decreased sensitivity to a continued stimulus (Like how you eventually stop smelling something after a while)
What is sensory adaptation
400
These are two examples of neuroglia and their function.
What are: Astrocytes: support cells, control extracellular environment of neurons – Blood-Brain Barrier Microglia: “immune system” of the CNS Ependymal cells: ciliated, involved with production of Cerebral Spinal Fluid (CSF) and CSF movement Oligodendrocytes: responsible for the myelin (IN CNS)
400
This is a network of branching nerves which interact with each other.
What is a plexus
400
This is the largest cranial nerve, it is also primarily sensory.
What is the trigeminal nerve
400
These receptors provide information about the precise position and the rate of movement of various body parts, the weight of an object being held in the hand and the range of movement of a joint.
What is proprioceptors
500
These are thee differences between an action potential and a graded potential. (Must specify which is which)
What is: Graded potentials can summate Graded potentials have no refractory period Graded potentials decrease in magnitude as they spread Action potentials only result from membrane potential change (threshold)
500
This is how the Golgi Tendon Reflex works (Explain it)
What is the Golgi Tendon Organ, located in the tendon of a muscle sense tension on the tendon and force relaxation of the muscle.
500
This is part of the cerebrum and diencephalon and functions in emotion and memory.
What is the limbic system.
500
This tract in the spine crosses over right away (meaning pain in the left leg is processed on the right side of the brain)
What is the anterior spinothalamic tract
