|
Recticular Formation |
Core of brain stem, motivation, decision making, mood, sleep/wake cycle, pain modification |
|
|
Medulla |
Connects spinal cord with rest of CNS, contains dorsal respiratory nuclei, role in motor regulation/learning |
|
|
Pons |
Largest portion, connects to/from cerebellum, injury results in coordination/balance deficits; injury within results in locked-in syndrome |
|
|
Inferior colliculus |
Part of midbrain; auditory relay nuclei |
|
|
Superior colliculus |
Part of midbrain; visual relay nuclei |
|
|
Substania nigra |
Part of mid brain; dopamine production, connects of basal ganglia |
|
|
Red nucleus |
Part of mid brain; Motor coordination of upper extremities |
|
|
Brain stem |
Connecting link between spinal cord and brain; controls basic involuntary movement; damage is fatal |
|
|
Diabetes insipidus |
Inadequate production of vasopression by hypothalamus and posterior pituitary |
|
|
Thalamic pain |
Intense; not responsive to medication |
|
|
Thalamic syndrome |
Hemianesthesia, sensory ataxia, and Thalamic pain |
|
|
Subthalamus |
Between thalamus and midbrain |
|
|
Epithalamus |
Above thalamus, includes pineal gland(melatonin production) |
|
|
Reticulospinal tracts |
Neurons descend directly to brainstem/spinal cord; synapse into autonomic neurons and enable hypothalamus to control ANS |
|
|
Pituitary gland |
Neuroendocrine junction |
|
|
Hypothalamus |
Controls ANS, regulates the endocrine system, regulates water balance, sleep/wake cycle |
|
|
Reticular nuclei |
Determine which signals will be conveyed to cerebral cortex, dysfunction makes it difficult to determine what's relevant |
|
|
Intralaminar nuclei |
Connections to the basal ganglia and the endocrine system; aides in conscious awareness |
|
|
Association nuclei |
Receives action potential from all over CNS; sensory input to emotional response |
|
|
6 relay nuclei |
Thalamus; receive info from specific areas of nervous system and convey it to the cortex |
|
|
Thalamus |
Largest portion, either side of third ventricle; "executive assistant" |
|
|
Diencephalon |
Located above brain stem, has 4 parts |
|
|
Axonal sprouting |
grow new nerve endings to reconnect neurons whose links were injured or severed |
