Study Notes
Musculoskeletal System
- Protects delicate organs, supports the body, and allows movement.
- Skeleton functions:
- Provides structure and support for the body.
- Stores calcium and minerals.
- Anchors and protects organs.
- Knee bones:
- Femur: Bears body weight, enabling movement and standing.
- Ligaments: Maintain structure, stability
- Cartilage: Provides protective cushion to the joint & bones.
- Tibia: Receives and distributes weight from the knee to the ankle.
- Skeletal muscle:
- Tendons: Connect muscles to bones.
- Muscles: Function in pumping blood and supporting heavy movements.
- Muscle fibers: Coordinate muscle contraction and produce movement force.
- Bundles of muscle fibers: Control coordinated muscle contraction and movement.
Nervous System
- Senses the environment, coordinates appropriate responses, and carries messages throughout the body
- Parts and Functions:
- Central Nervous System: Brain and spinal cord; controls body functions, integrates/processes incoming information.
- Peripheral Nervous System: Connects the brain and spinal cord to the body; transmits sensory information and motor commands.
- Neurons: Carry information towards/away from the central nervous system.
- Axon: Carries information away from the cell body.
- Dendrite: Receives electrical signals and brings them to the cell body.
- Connective tissue: Supports and protects all tissues and the body as a whole.
- Bundles of nerve cells : Collection of axons, transmits signals between the central nervous system and other parts of the body.
- Spinal cord: Contains nerves traveling to and from the body and brain.
- Brain: Organ inside the skull that controls all body functions.
- Sensory receptors: Transmit information from the five senses to the nervous system.
