Nervous System

The nervous system is a communication network connecting the brain to the body, enabling thought, feeling, and movement.
Organs: Brain, spinal cord, sensory organs, and nerve cells (neurons).
Central Nervous System (CNS): Brain and spinal cord; processes and interprets sensory information; controls actions, thoughts, and feelings.
Peripheral Nervous System (PNS): Nerves, somatic nervous system (voluntary movement), and autonomic nervous system (involuntary movement).
Neurons:
- Dendrites: Receive messages from other neurons.
- Axon: Carries impulses away from the cell body to other neurons or body parts.
- Synapse: Gap between neurons where messages are passed.

Skeletal System

Main Function: Provides shape and support, protects organs, allows movement with joints and muscles, and produces blood cells.
Structures: Bones (living cells, blood supply, nerves), cartilage, ligaments (connect bone to bone).
Bone Composition: Living cells, blood supply, and nerves.

Locomotive System (Musculoskeletal System)

Enables movement through the coordinated action of muscles and bones.
Includes: Skeletal system (bones, joints, ligaments) and muscular system (skeletal muscles, tendons).
Functions: Movement, support, protection, and coordination.
Muscle Types:
- Skeletal Muscles: Voluntary muscles attached to bones; examples include biceps and quadriceps.
- Smooth Muscles: Involuntary muscles found in organs (e.g., stomach, intestines).
- Cardiac Muscles: Found only in the heart; responsible for pumping blood.

Explore the fundamental concepts of the nervous and skeletal systems in this quiz. Understand how these systems work together to facilitate communication, movement, and support within the body. Dive into the roles of the brain, spinal cord, and bones while testing your knowledge on key terms and functions.
