Study Notes
Function of the Nervous System
- Manages all motor, sensory, autonomic, cognitive, and behavioral activities.
- Essential for communication between systems and maintaining homeostasis.
Structures of the Neurologic System
- Central Nervous System consists of the brain and spinal cord.
- Peripheral Nervous System includes cranial and spinal nerves, with autonomic and somatic systems.
- Neurons serve as the basic functional unit, with disease processes linked to neuronal damage.
Neurotransmitters
- Deficits in neurotransmitters can lead to various disorders.
- Facilitate communication between neurons and target tissues, controlling processes through potentiation, termination, or modulation.
- Parkinson's disease is caused by the loss of dopamine-producing nerve cells, affecting muscle function and coordination.
Major Areas of the Brain
- Comprises three key areas: Cerebrum, Brain Stem, and Cerebellum.
Cerebrum
- The largest brain area, divided into two hemispheres, includes the thalamus, hypothalamus, and basal ganglia.
- Four lobes:
- Frontal Lobe: Concentration, memory, motor function, and Broca’s area (speech production). Damage can alter personality and judgment.
- Parietal Lobe: Processes sensory information, proprioception, and spatial orientation.
- Temporal Lobe: Handles auditory processing and memory of sounds; damage affects language comprehension.
- Occipital Lobe: Responsible for visual interpretation and recall; damage can lead to vision loss or distortions.
Hypothalamus
- Connects to the pituitary gland; regulates autonomic nervous system activities.
- Oversees hormone secretion related to fluid balance, temperature regulation, appetite, sleep-wake cycles, and emotional responses.
Brain Stem
- Critical for life-sustaining functions; contains three main parts:
- Midbrain: Processes sensory and motor pathways and coordinates reflexes for auditory and visual stimuli.
- Pons: Supports sensory and motor pathways and plays a role in respiration regulation.
- Medulla Oblongata: Manages reflex centers for respiration, blood pressure, heart rate, and protective reflexes like coughing and swallowing.
Cerebellum
- Coordinates smooth movement and balance; crucial for proprioception and spatial awareness.
- Injury may present behaviors resembling intoxication, including unsteady gait and disorganized speech.
Meninges and Related Structures
- Dura Mater: Outermost layer, tough and inelastic.
- Arachnoid Mater: Middle layer, thin and delicate, loosely adheres to the brain and spinal cord, avascular.
- Pia Mater: Innermost layer, tightly covers brain and spinal tissue, highly vascularized.
