Study Notes
Overview of the Central Nervous System
- The spinal cord is involved in somatic and visceral motor functions, reflexes, and somatosensory functions such as touch and temperature sensation.
- The brain stem, comprising the medulla, pons, and midbrain, regulates autonomic functions, balance, and relay of sensory information.
- The cerebellum integrates sensory and motor information for coordination of movement, posture, and head and eye movements.
- The thalamus processes sensory information to the cerebral cortex and motor information from the cortex to the brain stem and spinal cord.
- The hypothalamus regulates body temperature, food intake, water balance, and hormone secretion from the pituitary gland.
- The cerebral hemispheres are responsible for perception, higher motor functions, cognition, memory, and emotion.
- The cerebral cortex, consisting of four lobes, is involved in various sensory and motor functions.
- The basal ganglia receive input from the cerebral cortex and regulate movement through projections to the motor cortex.
- The hippocampus is involved in memory, while the amygdala is associated with emotions and the autonomic nervous system.
- Neurons have dendrites for receiving information and axons for transmitting it through the nervous system.
- Sensory systems receive information through specialized receptors and transmit it to the central nervous system through a series of neurons and synaptic relays.
- Receptors for different sensory modalities, such as visual, auditory, and somatosensory, are activated by specific stimuli and undergo sensory transduction to generate receptor potentials.
