Week 1 Flashcards
Cognitive communication disorder
Impaired cognition
Aphasia (type of disorder)
Language Disorder
Apraxia of Speech (type of disorder)
Motor planning disorder
Dysarthria (type of disorder)
Motor programming disorder
Neurons and what they do.
Fundamental units of the nervous system.
Receive sensory input, sends motor commands, transforming and relaying the electrical signal
3 main parts of a neuron
dendrites, axon, cell body
Dendrite (function)
gets the signals from other neurons
Axon (function)
sends the signal to the next neuron. covered in myelin sheath to help with signal transmission.
Cell Body (function)
processes the signal received from the dendrite
Parts of the CNS
brain (cerebrum, cerebellum, brain stem)
spinal cord
Parts of the PNS
Cranial nerves (12), spinal nerves (31)
Damage to the CNS causes…
Apraxia
Damage to the PNS results in…
Dysarthria
Role of cerebrum(brain)
Controls every high function in the brain. It is the hard drive that saves everything.
What does the brain contain?
2 hemispheres, 4(5) lobes, 3 meningeal linings, cerebrospinal fluid (CSF)
3 meningeal layers and what they do.
Meninges protect and hold the shape of the brain.
Dura (outer most layer)
Arachnoid (middle layer)
Pia Mater (inner most layer)
Role of the CSF
protection, nutrients, gets rid of waste. Replenishes every 4-6 hours
Explain neuroplasticity
Once neurons die, they cannot heal. This is the training of surviving neurons to take on new functions. If we don’t do therapy and they have nothing to do, they also die.
Gray Matter (aka …)
Cerebral Cortex
Full of neuron cell bodies
