Terms
a condition in which not enough blood supply is reaching the neurons.
Hypoxia
Bundles of axons and their sheaths that extend from the CNS
What are Nerves
Transmits action potentials from the sensory organs to the CNS
What are Afferent Neurons
Part involved in the sense of hearing and in the sense of sight
the auditory area that makes sense of “speech.”then it goes to the auditory center so we can hear pitch and volume, then it goes to the auditory associated area to be put in historical context. Then it goes to this area so we can comprehend speech
What is the Wernicke's Area
not enough glucose in the body causing unclear thinking
What is hypoglycemia
bundles of parallel axons and their sheaths
What is White Matter
transmits action potentials from the CNS to the effector organs
What are Efferent Neurons
Relay station. Affects mood(such as emotions of fear and anger) and body movements
What is the Thalamus
subsection of the pre-motor area, Works out detailed sequencing that needs to take place to carry out the finest muscle movements. Those related to speech
What is the Broca's Area
blood -brain barrier
What are Astrocytes
collections of nerve cell bodies
What is Gray Matter
prepares the body for physical activity: fight or flight.
What is the Sympathetic Division System
involved in emotional functions. Tiny, inferior to the thalamus. Regulates the pituitary gland, also body temperature. Scientists did experiments using rhesus monkeys
What is the Hypothalamus
dedicated to our ability to reason and think things through. A big part of our personality is located here in addition to prefrontal lobotomies.
What is the Prefrontal Area
a blood clot cuts off blood to the brain
What is an Ischemic Stroke
Nerves that originate from the brain
What are Cranial Nerves
regulates the body for resting and digestion.
What is the Parasympathetic Division
Biggest part of brain function. “Higher level brain functions.”Has the cortex, the folds are called gyri which increase surface area.
What is the Cerebrum
crossing over, occurs in the medulla. Right half of the brain controls the left.
What is Decussation
blood vessel in the brain bursts
What is a Hemorrhagic Stroke
Nerves that originate from the spinal cord.
What are Spinal Nerves
The connective tissue of the nervous system
What is Neuroglia
Functions without conscious thought. “The control center of subconscious motor functions.” Muscle tone, equilibrium, muscle contractions, muscle preset and dampening.
What is the Cerebellum
allows the two hemispheres of the brain to communicate. Left side: More involved with speech, Right side: determines spatial relations such as music and face recognition
What are Commissures
