chap 1 Flashcards
Arousal
ability to respond to stimuli through our senses
Attending
ability to direct attention to stimuli; includes attention skills, figure-ground skills, perception
Orientation
ability to know who you are, where you are, and when you are
Declarative memory
ability to remember facts
Expressive language
Words we assign to our ideas to express the meaning of our thoughts to others
Receptive language
Ability to understand spoken and written language
Three gross divisions of the brain
Cerebrum, Brainstem, and Cerebellum
Lateral
Away from midline
Medial
Toward the midline
Superficial
Toward surface
Deep
Away from surface
Prone
Lying on belly
Supine
Lying on back
Neuroanatomy
Study of structure of the nervous system
Afferent
moving toward the central nervous system
Efferent
moving away from the central nervous system
Ipsi
same
Contra
opposite
Glia function
support cells
Proximal
close to a reference
Distal
far from a reference
Sulci
in folding
Gyrus
out folding
Adduction
moving toward midline
Abduction
moving away from midline
Thalamus
Mediates sensation to cerebral cortex
Basal ganglia
Regulates motor movements and muscle tone
Central nervous system (CNS)
Brain and spinal cord
Peripheral nervous system (PNS)
Nerve tracts that connect the rest of the body to the CNS
Neurons
Cells responsible for transmitting and processing information
Neuroglia
Provide structural support and important background functions for neurons
Motor
Transmit efferent information from brain to body
Sensory
Transmit afferent information from body to brain
Oligodendrocytes
Produces myelin within the central nervous system
Astrocytes
Forms glial scar to restrict inflammation
Microglia
Immunological cells
Schwann cells
Produces myelin for the peripheral nervous system
White matter
Axons of neurons covered in a white sheath of a protein and fatty substance called
myelin
Grey matter
Processes and regulates information in the CNS
Three gross types of white matter tracts
Association fiber, Commissural fibers, and Projection fibers
Association fibers
Connect different structures/areas within a single cerebral hemisphere
Commissural fibers
Connect analogous areas between two cerebral hemispheres
Projection fibers
Project from the brain to the spinal cord
