Quick Recap: Nervous System and Skeletal System
Nervous System 🧠
- What it Does:
- Acts as the control center of the body.
- Manages all voluntary (like walking) and involuntary (like breathing) actions.
- Sends signals between the brain, spinal cord, and body.
- Main Parts:
- Brain:
- Cerebrum: Thinking, memory, emotions, and voluntary actions.
- Cerebellum: Balance and coordination.
- Medulla: Controls involuntary actions like breathing and heartbeat.
- Spinal Cord:
- A highway of nerves carrying messages between the brain and body.
- Nerves:
- Sensory Nerves: Carry messages from sense organs to the brain.
- Motor Nerves: Send orders from the brain to muscles.
- Mixed Nerves: Handle both sensory and motor messages.
- Brain:
- Reflex Actions:
- Quick, automatic responses (e.g., pulling your hand away from a hot surface).
- Care Tips:
- Eat brain-friendly foods (nuts, fish, leafy greens).
- Stay active, sleep well, and protect your head with helmets.
Skeletal System 🦴
- What it Does:
- Provides structure and support to the body.
- Protects vital organs (e.g., the ribcage protects the heart and lungs).
- Works with muscles to enable movement.
- Main Parts:
- Bones:
- Adults have 206 bones; babies are born with 300 (some fuse as they grow).
- Joints:
- Hinge Joint: Elbows and knees (one-direction movement).
- Ball-and-Socket Joint: Shoulders and hips (movement in all directions).
- Pivot Joint: Neck (rotational movement).
- Gliding Joint: Wrists and ankles (sliding and twisting).
- Cartilage:
- Covers bone ends to reduce friction.
- Ligaments:
- Connect bones at joints.
- Bones:
- Fun Facts:
- The smallest bone is the stapes (in the ear).
- The femur (thigh bone) is the longest and strongest bone.
- Care Tips:
- Eat calcium-rich foods (milk, cheese) and get Vitamin D.
- Exercise regularly and maintain good posture.
- Stay safe with protective gear during activities.
