Study Notes

Skeletal System

Comprises a rigid framework of bones providing body support and protecting internal organs.
Connective structures include:
- Ligaments: Strong tissue connecting bones to one another.
- Tendons: Connective tissue that attaches muscles to bones.
- Cartilage: A stiff tissue that supports joints and provides flexibility.

Muscular System

Composed of muscles and tendons responsible for body movement through energy exertion.
Types of muscles:
- Skeletal Muscles: Voluntary muscles that facilitate movement.
- Cardiac Muscles: Involuntary muscles found in the heart.
- Smooth Muscles: Involuntary muscles, found in organs.

Nervous System

A complex network of nerves coordinating bodily actions and transmitting messages.
Divided into two main parts:
- Central Nervous System (CNS): Includes the brain and spinal cord; manages body functions and information exchange.
- Peripheral Nervous System (PNS): Includes all other nerves and endings; transmits sensory information to the CNS and receives responses.

Important Concepts and Definitions

Epilepsy: Not a degenerative disorder of the spinal nervous system; true or false answer is false.
Healthy Skeletal System Maintenance: Regular exercise and a balanced diet are essential for overall skeletal health.
Sense of Smell: Governed by the nervous system.
Migraine Headaches: Classified as common disorders of the CNS.
Electrical Impulse Pathway: After stimuli (e.g., touching a hot pot), signals travel from the hand nerves to the spinal cord, then to the brain and back.
Muscle Atrophy: Refers to a muscle that has shrunk in size.

Quiz and Review Points

Cardiac muscles are categorized as involuntary smooth muscles.
Groupings of muscles for presentations should include skeletal, cardiac, and smooth muscles.
The skeletal system does not directly affect the body's ability to fight infections.
