Pathology of what part of the brain is often associated with Parkinson’s disease, Huntington’s disease, Tourette’s syndrome?
Basal ganglia
This part of the brain includes the cerebral aqueduct, periaqueductal gray, reticular formation, substantia nigra, red nucleus
midbrain - tegmentum
What part of the brain is involved with fear, pleasure responses, arousal, processing memory, formation of emotional memories?
Amygdala
What part of the brain influences autonomic nervous system acuity and regulates respiration and heart rate?
Medulla oblongata
What nervous system is involved in the control and expression of mood, emotion, memory, and appetite?
Limbic system
patients with cerebellar pathology present with what pathologies?
ataxia
dysmetria
what part of the brain is responsible for coordination and motor behavior, in addition to balance, motor learning, and motor control?
cerebellum
reflex center for visual, auditory, and tactile responses.
midbrain
what does parasympathetic activation do?
decreases heart rate, cardiac contractility, and stroke volume
what part of the brainstem part of the brainstem and regulates respiration rate as well as orientation of the head in relation to visual and auditory stimuli.
pons
where is the conus medullaris , where spinal cord ends?
L2
what part of the forebrain is involved in initiation and regulation of gross intentional movements, planning and execution of complex motor responses, facilitation and inhibition of motor responses, and the ability to accomplish automatic movements and postural adjustments?
basal ganglia
what part of the brain functions to regulate the autonomic nervous system (e.g., stress response, sleep, appetite, body temperature, fluid balance and emotions).?
hypothalamus via pituitary gland using endocrine system
what term is Alpha motor neurons (large motor neurons of the brain stem and spinal cord) and the muscle fibers it innervates?
motor unit
