Behavioral Neuroscience Exam #1
What makes up the Central Nervous System? - ANSWER-Brain and the spinal cord
What is the defining difference between the CNS and the PNS? - ANSWER-Bone
What is the CNS? - ANSWER-The part of the nervous system encased in the bony protection of the spine and skull
Afferent information - ANSWERSensory iformation coming into the CNS
Efferent information - ANSWERInformation leaving the CNS
Dermatome - ANSWERArea of the skin supplied with afferent nerve fibers by a single spinal cord dorsal root
Sympathetic nervous system - ANSWER-Arouses the body for action by increasing heart rate and blood pressure
-Mediates the "fight or flight" response
Parasympathetic system - ANSWER-Opposite of sympathetic nervous system that prepares the body to "rest and digest"
-Reverses the fight or flight response
Dorsal - ANSWERAbove sometimes referred to as superior
Ventral - ANSWERbelow sometimes referred to as inferior
Anterior - ANSWERFront sometime referred to as frontal or rostral
Posterior - ANSWERTail sometimes referred to as caudal
Medial - ANSWERMiddle
Lateral - ANSWERSide
What are the two branches of the PNS? - ANSWER1. The Somatic Division
2. The Autonomic Division
Somatic Nervous System - ANSWER-Conveys sensory information to the CNS and motor information from the CNS to the muscles
-Transmits sensation & produces movement Autonomic Nervous System - ANSWER-Enables the CNS to govern the workings of the
internal organs (heartbeat, respiration)
-Balances internal functions
What are the two divisions of the Somatic Nervous System? - ANSWER1. Cranial nerves
2. Spinal nerves
What are the two divisions of the Autonomic Nervous System? - ANSWER1. Sympathetic Nervous System
2. Parasympathetic Nervous System
What is the Dermatome? What nervous system is it apart of? - ANSWER1. The area of skin supplied with afferent nerve fibers by a single spinal cord dorsal root
Coronal Section Cut - ANSWER-Cut in a vertical plane, from the crown of the head down, yielding a frontal view of the brain's internal structures
-(Cutting the front of the face off)
Horizontal Section Cut - ANSWER-Cut along the horizon, with a view looking down on the brain from above
-(Cutting off the top of the head)
Saggital Section Cut - ANSWER-Cut lenghtways from front to back and viewed from the
side
-(Cut down the center of the face)
-If the cut is directly down the middle and separates the two hemispheres of the brain it is called a midsaggital cut
What are the four lobes of the brain? - ANSWER1. Frontal lobe
2. Parietal lobe
3. Temporal lobe
4. Occipital lobe
What is the function of the Frontal lobe? - ANSWER-Executive functioning such as decision making, social interactions, & Morality
-Movement
What is the function of the Parietal lobe? - ANSWER-Somatosensation (touch)
-Sensory intergration
What is the function of the Temporal lobe? - ANSWER-Audition (hearing)
-Olfaction (smell)
-Gustation (taste)
-Language
-Memory
