Thalamic nuclei
Brain region-
General functions-
Associated disorders-

Brain region- thalamus (diencephalon)

General functions- transmission of signals from other regions of CNS to the cerebral cortex mediating sensory, motor, cognitive, and affective (emotional) functions

Associated disorders- disruption and possible loss of sensory, motor and other functions

32

Hypothalamic nuclei
Brain region-
General functions-
Associated disorders-

Brain region- hypothalamus (hypothalamic nuclei)

General functions- visceral (feeding, drinking, autonomic, and endocrine functions and sexual and emotional behavior)

Associated disorders- disruption, loss, or alterations in visceral and affective functions and processes

33

Hippocampal formation, amygdala, septal area, cingulate gyrus, prefrontal cortex
Brain region-
General functions-
Associated disorders-

Brain region- limbic structures

General functions- modulation of hypothalamic functions; regulation of emotional behavior, short-term memory

Associated disorders- temporal lobe epilepsy; loss of control of emotions and related affective processes; loss of short term memory

34

Cerebellum: anterior, posterior and flocculonodular lobes
Brain region-
General functions-
Associated disorders-

Brain region- cerebellum and brainstem

General functions-integration of motor functions related to all regions of CNS associated with motor and related processes

Associated disorders- loss of balance; ataxia; hypotonia; loss of coordination; disorders of movement when intentionally attempting to produce a purposeful response

35

Midbrain
Brain region-
General functions-
Associated disorders-

Brain region- cerebellum and brainstem

General functions- transmission and regulation of sensory, motor, and autonomic functions (CN III and IV)

Associated disorders- sensory, motor, and autonomic deficits as well as deficits associated with CN III and IV

36

Pons
Brain region-
General functions-
Associated disorders-

Brain region- cerebellum and brainstem

General functions- transmission and regulation of sensory, motor, and autonomic functions (CN V, VI, and VII)

Associated disorders- sensory, motor, and autonomic deficits as well as deficits associated with CN V, VI, VII

37

Medulla
Brain region-
General functions-
Associated disorders-

Brain region- cerebellum and brainstem

General functions- transmission and regulation of sensory, motor, and autonomic functions (CN VIII, IX, X, XII)

Associated disorders- sensory, motor, and autonomic deficits, including respiration, as well as deficits associated with CN VIII, IX, X, XII

38

What is the spinal cord white matter made of mostly?

almost entirely axons and dendrites

39

What is the only CN to exit the brainstem from the dorsal/posterior aspect?

The trochlear nerve (CN IV) is the only cranial nerve to exit the brainstem from the dorsal/posterior aspect.
