2 Functions of hypothalamus
Control of autonomic nervous system
Control of endocrine system
4 Examples of functions of hypothalamus
Control emotional behavior
Control food intake
Control water intake
Regulation of sleep wake rhythms
What are functions of broca area
Regulate skeletal muscle movement involved with speech
Functions of wernicki areas
involved in recognizing, understanding, and comprehending spoken and written language
How do broca and wernicki area work together
Works with each other for fluent communication
Three major regions of brain stem from superior to inferior
Midbrain
Pons
Medulla oblongata
Function of midbrain
Issues involuntary motor commands to help maintain posture
2 Function of pons
Regulate the skeletal muscles of breathing
Involved in pathway for sound localization
Function of medulla oblongata
All tracts between brain and spinal cord through here
Function of superior colliculi of tectal plate
Visually track moving objects and control visual reflexes
Function of inferior colliculi of tectal plate
Control reflexive turning of head and eyes in direction of a sound
2 Function of substantia nigra
Houses neurons that produce dopamine
Movement, emotions, pleasure, and pain
What disease results of degeneration neurons in substantia nigra
Parkinson’s disease
Severe injury to medulla oblongata would likely result in?
Death
What happens to most of the axons of the corticospinal tracts at the decussation pyramids of medulla oblongata
Cross to opposite side of brain
What is the result of crossover at decussation of the pyramids
Each cerebral hemisphere controls the voluntary movement of opposite side of body
Describe internal anatomy of cerebellum
Partitioned into three regions:
Cerebellar cortex- outer gray matter of cortex
Arbor vitae- internal region of white matter
Deepest gray matter of cerebellum nuclei
What are folia in cerebellum
