Brain and Spinal Cord basics Flashcards
The Medulla controls what?
breathing and heart rate
What are the functions of the Pons?
conveys messages from the cortex and the cerebellum
connects cerebellum with cerebral cortex
necessary for dreaming
What is the cerebellum necessary for?
balance and coordinated movements
What is the Mid brain’s important functions?
necessary for visual processing and auditory reflexes
What is the reticulated formation responsible for controlling?
sleep and wakefulness
What is the cerebral cortex?
Spongy outer layer of brain
What important functions do we need the hippocampus for?
memory
survival behaviors like agression, sexual activity/motivation and hunger/thirst
basic autonomic nervous system function
helps endocrine system
What are the four areas of the Limbic system?
The Thalamus, hypothalamus, amygdala and hippocampus.
What are the functions of the Thalamus?
sensory relay station
What does the basal ganglia control?
motor function and planning
What is the corpus collosum responsible for?
connects right and left hemispheres
sends messages between the two hemispheres
What is the primary function of the occipital lobe?
visual processing
What are the four important functions of the frontal lobe?
executive function
personality
important thinking and problem solving
important for motor cortex function
What are the functions of the Temporal lobe?
language acquisition
processes auditory information and info about ourselves
What are the four brain structures included in the cortex?
Frontal Lobe
Parietal Lobe
Temporal Lobe
Occipital Lobe
What are the three primary structures that make up the brain stem?
Midbrain
Pons
Medulla
What two cortexes make up the central sulcus?
Primary sensory cortex
motor cortex
The peripheral nervous system contains:
somatic nervous system
autonomic nervous system
sympathetic/parasympathetic nervous system
all nerves not in the brain or spinal cord
The three kinds of neurons included in the peripheral nervous system are:
Sensory neurons
inter neurons
motor neurons
Where are inter neurons located?
in the spinal cord where it connects to the peripheral nervous system
What is the function of sensory neurons?
process incoming information
Where are motor neurons located?
between spinal cord and muscle tissue
What is the somatic nervous system responsible for?
big movements
big muscles
movements like standing up or sitting down
What is the autonomic nervous system responsible for?
heart muscle (small muscles) internal activity of neurons that we don't necessarily think about controlling like the lungs
