Study Notes
Nervous System Overview
- The nervous system receives and sends out information about the environment.
- It monitors and responds to changes in the body.
Neurons
- A neuron is a specialized cell transmitting nerve impulses.
- Electrical signals change + and – charges from one end of a neuron to the other.
- Chemical signals allow signals to go from one neuron to another by "jumping the gap" (synapse).
Types of Neurons
- Sensory neurons conduct impulses inwards to the brain or spinal cord for touch, odor, taste, sound, and vision.
- Interneurons are responsible for processing and integrating information within the nervous system.
- Motor neurons transmit signals from the CNS to muscles and glands to control movement and function.
Central Nervous System (CNS)
- The CNS consists of the brain and spinal cord.
- The brain is well protected by the skull and meninges.
- Cerebrospinal fluid (CSF) cushions the brain and spinal cord from injury and serves as a delivery and waste removal system for the brain.
Brain Structure
- The lobed mass of grey matter buried under the cerebral cortex is called the basal ganglia.
- The thick band of nerve fibers that divides the cerebrum into left and right hemispheres is called the corpus callosum.
Brain Functions
- The Frontal Lobe is associated with reasoning, planning, parts of speech, movement, emotions, and problem solving.
- The Temporal Lobe is associated with perception and recognition of auditory stimuli, memory, and speech.
- The Occipital Lobe is responsible for visual processing.
- The Cerebellum controls motor movement and coordination.
Injuries
- A spinal cord injury can result in the inability to move or function.
- Brain damage can result in cognitive, emotional, and motor impairments.
