Study Notes
Fore-brain Functions
- The fore-brain is the primary region responsible for thinking and processing sensory information.
- Specialized areas within the fore-brain are dedicated to specific senses, including hearing, smell, and sight.
- Association areas integrate sensory data with stored information to facilitate decision-making regarding responses.
Sensory and Motor Coordination
- Decisions from the fore-brain are communicated to motor areas that manage voluntary muscle movement, such as leg muscles.
- Sensations like feeling full originate from a hunger center in the fore-brain, separate from basic senses.
Involuntary Actions
- Involuntary muscle movements are regulated by the mid-brain and hind-brain, which operate without conscious thought.
- The medulla, located in the hind-brain, controls vital involuntary functions like blood pressure, salivation, and vomiting.
Role of the Cerebellum
- The cerebellum, part of the hind-brain, is crucial for maintaining balance, posture, and precision in voluntary movements.
- Everyday activities, like walking straight or riding a bicycle, depend on the cerebellum for coordination.
Nervous System Overview
- Nervous tissue is essential for collecting, processing, and relaying information throughout the body.
- It makes decisions based on sensory input and communicates those decisions to the muscles for execution.
Mechanism of Muscle Movement
- Muscle movement occurs when a nerve impulse reaches the muscle fibers, leading to their contraction.
- Muscle cells achieve movement by altering their shape, primarily through the action of specific proteins responding to nervous impulses.
Cellular Dynamics of Muscles
- Muscle cell shape change, fundamental to contraction, is regulated by the chemistry of cellular components.
- Special proteins within muscle cells rearrange in response to electrical signals from nerves, resulting in contraction and shortening of the muscle fibers.
