Musculoskeletal System - Coggle Diagram
Musculoskeletal System
the organization of the skeletal system
The skeletal system is divided into two parts: axial (head, neck, chest, and back) and appendicular (limbs).
The axial skeleton protects vital organs, while the appendicular skeleton enables movement.
Adults have 206 bones; fusion occurs during growth.
Key functions include support against gravity and providing a framework for muscle movement.

the structure and function of skeletal muscle
Structure:
Long muscle fibers.
Myofibrils with sarcomeres.
Function:
Voluntary body movement.
Support and stability.
Nervous system control.
the movement control pathway
Brain sends commands.
Signals to muscles.
Muscles move.
Sensory feedback to brain.
the process of skeletal muscle contraction and relaxation
Contraction:
Nervous signal initiates.
Calcium activates interaction.
Relaxation:
Myosin pulls actin.
Nervous signal stops.
Calcium decreases.
Interaction halts.
Muscle relaxes.
the energy source in muscle contraction
Muscle uses ATP for energy.
Creatine phosphate aids ATP.
Glycolysis and oxidative phosphorylation make ATP.
