Study Notes

Nervous System and Brain Anatomy Overview

The somatic nervous system is voluntary and regulates intentional processes, receiving sensory input through dorsal roots and delivering motor output via ventral roots to muscles.
The autonomic nervous system controls unconscious processes, including the sympathetic and parasympathetic nervous systems, which are activated during stress responses and rest and digest functions, respectively.
The lobes of the brain include the frontal, parietal, occipital, and temporal lobes, each responsible for different functions such as sensory processing and emotional processing.
The sympathetic nervous system is responsible for fight or flight responses, while the parasympathetic nervous system is responsible for relaxed states and non-emergency functions.
The amygdala is the fear center of the brain, and the prefrontal cortex plays a role in fawning and appeasing situations, overpowering the amygdala in these scenarios.
Communication in the nervous system occurs through peripheral nerves, hormones, and the hypothalamus and pituitary gland, which regulate hormone release.
The production of breast milk involves vasin and oxytocin for social bonding, and the brain is highly vascularized to ensure proper hormone secretion.
The blood-brain barrier regulates the passage of molecules to and from the brain, allowing only certain molecules to pass through.
Cerebrospinal fluid (CSF) acts as a cushion to protect the brain, is produced by the choroid plexus, and is reabsorbed by the arachnoid, playing a role in nourishment and protection.
The brain meninges, including the dura mater, arachnoid, and pia mater, provide protection to the brain and spinal cord.
Neurons and glial cells are the main types of brain cells, with neurons having various parts such as cell body, dendrites, axons, and presynaptic terminals.
Alzheimer's disease is associated with low levels of neurotransmitters for learning and memory, dendritic abnormalities, amyloid plaques in the brain, and memory loss.
