Smooth Muscle and Chapt 5. CNS Human Physiology

Across
Multi-unit smooth muscle has contractions initiated by the neurons. Contraction initiated only in response to nervous system stimulus.
Part of brain in charge of carrying out initial visual processing.
Organized into tracts, ascending and descending.
Type of nervous system innervating smooth muscle, cardiac muscle and glands.
Type of nervous system with motor neurons supplying the skeletal muscles.
Part of brain in charge of carrying out initial auditory processing.
Horn where cell bodies of interneurons on which afferent neurons terminate.
Relay station for all synaptic inputs to the CNS, provides a crude awareness of sensations, and provides a degree of consciousness.
Single-unit smooth muscle becomes excited and contracts as a single unit.
Cell adapts slowly to a stimulus and continues to produce action potentials over the duration of the stimulus. partially contracted at all times. All multi-unit smooth muscle is _____.
Lie between afferent and efferent neurons. Important in integrating peripheral information to peripheral responses.
Consists of the medulla, pons, and midbrain. The vital link between the spinal cord and higher brain regions.

Type of nervous system that gives rise to fight or flight response.
The brain area most directly involved in regulating the internal environment (homeostatic functions).
