Exam 1- Neuroanatomy
Terms in this set (52)
Controls vital functions such as heartbeat, circulation, and respiration. Relay afferent and efferent impulses.
Relay station. Breathing reflexes.
Heartbeat, breathing, and arousal. Associated with narcolepsy.
Associated with motor control, motor memory, especially ballistic movements, possibly attention, language, and emotion.
a "map" of which area of the body is effected and attached to the spine.
Tightly packed cells. Protects brain from pathogens in the blood. Active transport for large molecules.
Makes cerebrospinal fluid.
Hollow spots that hold CSF.
Brain and spinal cord.
Somatic and autonomic.
The idea that specific functions are located in particular places in the nervous system (ex: leg control).
The idea that some specific functions are largely localized in one hemisphere (ex: language; Broca's area).
Roof of the midbrain. Contains superior and inferior colliculi.
Visual attention and visuomotor control- perimetry (marker demonstration).
Floor of the midbrain. Contains the reticular formation, red nucleus, substantia nigra, and periaqueductal gray.
Movement. (In tegmentum).
Movement/dopaminergic pathway. Associated with Parkinson's.
Pain control, encephalin production.
Sensory relay nuclei (all senses except olfaction). Reciprocal connections.
Endocrine function. Moticated behaviors- maintaining homeostasis, the "internal milieu."
Pathways. Part of limbic system. Papez circuit= amygdala- MB- Thalamus. Recollective memory.
Characterized by cortex (gyri and sulci). Manages complex cognitive functions like reason and language.
Bundle of nerves that connects the two hemispheres.
Source of 8 hormones.
Regulates movement. Structures include the amygdala, globus pallidus, and caudate
Regulates motivated behaviors. Emotions as motivators. Memory. Associated with Alzheimer's.
Emotions, survival instinct, and memory. Associated with Parkinson's.
Contains the nucleus of a neuron. Connects to the dendrites. Performs all basic cell functions.
Receive action potential from other neurons and pass it through the soma.
Sends action potential away from the soma.
Contains vesicles that release NT, which perform different functions.
Fatty tissue that wraps around axon and increases the speed at which impulses travel.
Nodes of Ranvier
Allow for faster passage of impulse/action potential.
Executive function, planning, self-regulation, inhibition. At back/posterior is the motor cortex.
At front/anterior is the somatosensory cortex and association areas.
Auditory cortex, declarative memory storage.
Specialization for language. Broca's area and Wernicke's area.
Grammatical/motor linguistic processing.
Posterior parietal lobe- attention, neglect.
Controls automatic functioning.
Fight or flight.
Rest and digest.
May be connected to traumatic brain injury and PTSD.
