Study Notes
Neural Pathways and Sensory Systems Overview
- The spinal cord contains descending and ascending pathways related to somatic motor functions, visceral functions, reflexes, and somatosensory functions.
- The brain stem, consisting of the medulla, pons, and midbrain, regulates autonomic functions, balance, posture, eye movements, and auditory and visual systems.
- 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 cerebral 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, including the cerebral cortex, basal ganglia, and limbic system, are responsible for perception, higher motor functions, cognition, memory, and emotion.
- 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 regulates emotions and communicates with the autonomic nervous system via the hypothalamus.
- Neurons have dendrites for receiving information and axons for transmitting information through the nervous system.
- Sensory systems receive information from specialized receptors and transmit it through neurons and synaptic relays to the central nervous system.
- Different sensory modalities are detected by various receptors, such as mechanoreceptors, photoreceptors, chemoreceptors, thermoreceptors, and nociceptors.
- The conversion of stimuli into electrochemical energy, known as sensory transduction, is mediated through the receptor potential, which increases or decreases the probability of an action potential.
