Psych 381 Study Guide Exam 1 Larsen BYU || 100% Correct
Answers.
Hemispheres correct answers Brain contains two almost symmetrical halves: right and left
Cerebral Cortex correct answers Heavily folded outer layer of brain tissue composed of neurons
(cortex = "bark")
- Gyri: bumps on the folded surface
- Sulci: grooves of the cortex
- Fissures: a very deep sulcus
- 2.5 mm thick
The Brain correct answers 2 Hemispheres
4 Lobes per hemisphere
- Frontal
-Temporal
-Parietal
-Occipital
Dorsal correct answers Structures atop the brain or a structure within the brain
Ventral correct answers Structures toward the bottom of the brain or one of its parts
Lateral correct answers Structures located toward the side of the brain
Medial correct answers Structures toward the brain's midline
Anterior correct answers In front
Posterior correct answers At the back
Ventricles correct answers Lateral
3rd
4th
Cerebral Aquaduct correct answers Connects 3rd and 4th ventricles
Peripheral Nervous System (PNS) correct answers -All the neurons in the body that are located
outside the brain and spinal cord
-Somatic Division
-Autonomic Division
Somatic Division correct answers Conveys sensory information to the CNS and motor
information from the CNS to the muscles.
, Autonomic Division correct answers Enables the CNS to govern the workings of the internal
organs (e.g., heartbeat, respiration)
Central Nervous System correct answers Mediates behavior
-Brain
-Spinal cord
Somatic Nervous System correct answers Transmits sensation, produces movement
-Cranial nerves
-Spinal nerves
Spinal and cranial nerves carrying sensory info to the CNS. Also transmits motor instructions for
movement
Autonomic Nervous System correct answers Balances internal functions
-Sympathetic division (arousing)
-Parasympathetic division (calming)
Balances internal organs to "rest and digest" or to "fight or flee"
Axons.... correct answers Several axon fibers running together form a nerve when outside the
CNS or a tract within the CNS.
Forebrain: Three Principle Structures correct answers Neocortex
Basal Ganglia
Limbic System
Neocortex
Forebrain Structure correct answers Regulates various mental activities
Basal Ganglia correct answers Controls of voluntary movement
Limbic System correct answers Regulates emotions and behaviors that create and require
memory
Forebrain
Cortical Lobes correct answers Occipital: Vision
Parietal: Tactile functions
Temporal: Visual, auditory, and gustatory functions
Frontal: Motor and executive functions
Forebrain
Basal Ganglia correct answers Collection of nuclei just below the white matter of the cortex
-3 Principal structures: caudate nucleus, putamen, and globus pallidus
Controls voluntary movement
Related disorders
-Parkinson's disease and Tourette's syndrome
