Study Notes
Neuroanatomy and Autonomic Nervous System Overview
- Cortical sensory centers process information sent to the central nervous system (CNS) and elicit a response, with the brain displaying information from the left side of the body on the right side and vice versa
- Neuroplasticity allows the brain to reorganize sensory areas based on usage, with the homunculus representing individualized sensory perception
- Various types of sensory receptors provide different types of information, including mechano, thermo, chemo, photo, and nociceptors
- Receptors are categorized as exteroceptors, interoceptors, and proprioceptors, and can be simple or complex in structure
- Different areas of the body have varying receptor field sizes, affecting discrimination and sensitivity to stimuli
- The autonomic nervous system (ANS) consists of the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS)
- SNS triggers the "fight or flight" response, while PNS facilitates the "rest and digest" functions, aiming for a balanced coexistence
- Both SNS and PNS pathways involve ANS, with SNS releasing epinephrine and causing increased responses, while PNS decreases responses
- The SNS and PNS have opposing effects on target areas, with dual innervation in most body parts and exceptions like the kidney and adrenal medulla
- Cerebral control is contralateral, with the left hemisphere controlling the right side of the body
- Basal ganglia coordinates autonomic movement and muscle tone, while the limbic system is associated with emotion and feelings
- The brain's lobes have distinct functions, such as the frontal lobe managing skilled movement and executive functioning, the parietal lobe housing the sensory cortex, the occipital lobe controlling vision, and the temporal lobe handling memory and auditory functions.
