Study Notes
Nervous System Review
- The nervous system is divided into the Central Nervous System (CNS) and Peripheral Nervous System (PNS)
- The CNS includes the brain and spinal cord.
- The PNS includes the cranial nerves and spinal nerves.
Brain
- The forebrain includes the cerebrum, thalamus, and hypothalamus.
- The cerebrum is involved with higher brain functions, sensory information processing, motor function initiation, and information integration.
- The cerebrum is divided into frontal, temporal, occipital, and parietal lobes, each specialized for different functions.
- The lobes and their functions are detailed in supplementary material.
- Specialized areas within the cerebrum such as Broca's area and Wernicke's area are involved in language and speech.
- The limbic system is important for emotions, emotional bonding, and memory formation.
- The amygdala is part of the limbic system and plays a key role in recognizing emotional content from faces and expressions, and other stimuli.
- The hippocampus is integral to forming long-term memories.
Midbrain
- The midbrain contains tracts connecting the cerebrum and thalamus and plays a role in eye-muscle reflexes, auditory and visual processing. It connects head movements with visual and auditory stimuli.
- The midbrain includes the tectum, superior and inferior colliculi, substantia nigra, and red nuclei
Pons
- The pons connects the two halves of the cerebellum and controls breathing.
Medulla Oblongata
- This structure acts as an extension of the spinal cord; it contains nerve tracts going to and from the brain, and is where almost all cranial nerves originate
- It controls many subconscious activities like respiratory rate, heart rate, and blood vessel constriction. It also controls activities like swallowing, hiccupping, coughing, and sneezing.
Cerebellum
- The cerebellum is involved in maintaining equilibrium and coordinates movements.
Spinal Cord
- The spinal cord contains ascending and descending tracts of interneurons that communicate with afferent and efferent components of the nervous system.
- Afferent neurons enter the dorsal (back) side of the spinal cord while efferent neurons exit the ventral (front) side.
Cranial Nerves
- There are 12 pairs of cranial nerves that originate from the brain stem.
- The functions of each are listed in the supplementary material.
Peripheral Nervous System (PNS):
- The PNS is further subdivided into the sensory (afferent) and the motor (efferent) systems.
- The sensory system detects incoming sensations and signals from external and internal environments.
- The motor system sends signals to muscles and glands (effectors).
- The motor division is further subdivided into the somatic and autonomic systems. The somatic nervous system connects to skeletal muscles, whereas the autonomic nervous system is further divided into sympathetic and parasympathetic branches.
Autonomic Nervous System
- Sympathetic division: Fight or flight response; Its neurotransmitter is norepinephrine.
- Parasympathetic division: Rest and digest response; Its neurotransmitter is acetylcholine.
Pain pathways and gate control theory
- Gate-control theory explains how psychological factors can affect pain perception by opening and closing a neural gate in the spinal cord.
- The gate is located in the substantia gelatinosa of the spinal cord.
- Three factors involved in opening and closing the gate: the amount of activity in pain fibers, the amount of activity in other peripheral fibers, and messages that descend from the brain.
- Physical, emotional, and mental conditions can affect this gate.
Nursing Assessment of Nervous System Disorders
- Assessment of nervous system disorders may include:
- Main symptoms/signs (e.g., paresthesia, loss of consciousness)
- Medical history (e.g., hypertension, head trauma)
- Activities of daily living (ADL) assessment
- Physical assessment (e.g., muscle strength, reflexes, cranial nerves)
- Diagnostic examinations (e.g., X-rays, CT scans, MRIs, EEGs).
