    Study Notes

    Neuroscience and Nervous System Overview

    • The somatic nervous system, responsible for voluntary processes, receives sensory input through dorsal roots and delivers motor output via ventral roots to muscles.
    • The peripheral nervous system includes 12 pairs of cranial nerves and nerves in the cervical, thoracic, lumbar, and sacral regions.
    • The autonomic nervous system, which regulates unconscious processes, consists of the sympathetic and parasympathetic nervous systems.
    • The lobes of the brain include the frontal, parietal, occipital, and temporal lobes, each with distinct functions.
    • The sympathetic nervous system, part of the autonomic nervous system, is responsible for the fight or flight response and has short preganglionic nerves.
    • The parasympathetic nervous system is responsible for rest and digest functions and has long preganglionic nerves.
    • The amygdala is the brain's fear center, and the prefrontal cortex plays a role in fawning and appeasing situations.
    • The communication in the nervous system occurs through nerves, hormones, and the hypothalamus and pituitary gland.
    • The pituitary gland secretes hormones such as oxytocin and melatonin, impacting various bodily functions.
    • The brain communicates with the body through nerves and hormones, with arterial flow regulating hormone release from the pituitary gland.
    • Cerebrospinal fluid, produced by the choroid plexus, flows through ventricles and acts as a cushion to protect the brain during physical activity.
    • The brain's protective mechanisms include the dura mater, arachnoid, and pia mater, as well as cerebral spinal fluid, which provides nourishment and protection.
