|
CNS |
Brain and spinal cord |
|
|
PNS |
Cranial nerves and spinal nerves |
|
|
Neuroplasticity |
The brain's ability to reorganize/modify itself based on life experiences |
|
|
Upper motor neurons |
Motor neuron with its cell body in the cerebral cortex or brainstem that controls activation of lower motor neurons |
|
|
3 types of nerve cells |
Sensory, motor, and autonomic |
|
|
Proprioception |
The body's sense of position and location in space |
|
|
Lower motor neurons |
A nerve cell that forms a synapse with skeletal muscle and is part of a peripheral nerve (cranial or spinal nerve) |
|
|
Peripheral nerves can be injured by...? |
Trauma, compression, or damage by disease |
|
|
Cerebrum |
Largest part of the brain; responsible for thought emotion, and language |
|
|
Diencephalon |
Connects other brain areas to the cerebrum and controls physiological responses |
|
|
Cerebellum |
Located behind the pons and behind the occipital lobes; Responsible for balance and coordination |
|
|
3 parts of the brainstem |
Midbrain, pons, and medulla oblongata |
|
|
Thalamus |
Located superior to the hypothalamus; transmits nerve impulses to cortex |
|
|
How does neuroplasticity manifest itself in the brain? |
When injured, the brain creates new pathways (rewires itself) to re-establish function |
|
|
Location and function of the spinal cord |
Location :runs from the top of the neck to the upper lumbar part of the spine. Function: connects brain to peripheral nerves. |
|
|
Injury to spinal cord |
Traumatic, tumors, or disease. Since it is part of CNS, nerves cannot regenerate which can cause paresis or paralysis |
|
|
Reflexes |
Formed by interconnected nerves in spinal cord; Allows for very rapid, involuntary responses to sensations |
