Skeletal
What are the five main roles of the skeletal system?
Protection, support, supply, storage, movement.
What are the three main types of muscles?
Smooth, cardiac, skeletal
What is a neuron?
A nerve cell that carries information back and forth from the environment and the central nervous system (CNS).
How do the skeletal, muscular, and nervous systems support structure in the body?
They provide framework, enable movement, and coordinate body functions.
The femur provides what function?
Movement, support, storage, supply.
What is the primary function of the muscular system?
Movement.
What does the cerebellum do?
Controls the body's positioning and balance.
How do the skeletal and muscular systems work together for movement?
Muscles pull on bones to create movement.
The skeletal system produces white blood cells that play an important role in what other system?
Immune system
Tendon.
What is the central nervous system composed of?
Brain and spinal cord.
What role does the nervous system play in controlling voluntary movements?
It sends signals to skeletal muscles to initiate movement.
What is the name of the soft tissue found inside bones that produces blood cells?
Bone marrow.
Identify a type of movement that is voluntary.
Skeletal muscle movements (e.g. walking).
Identify the name and function of the two systems within the peripheral nervous system (PNS).
Autonomic (involuntary action) and somatic (voluntary movement and reflexes).
How do the three systems work together to maintain balance?
The nervous system detects balance, the skeletal system provides structure, and the muscular system allows for adjustments.
Which part of the skeletal system protects the brain?
Skull
Identify a type of movement that is involuntary.
Smooth muscle movements (e.g. digestion).
The nervous system is made up of three parts. What are they?
Brain, spinal cord, nerves.
Explain how these systems interact when you catch a ball.
The nervous system detects the ball's position, the skeletal system positions the body, and the muscular system moves the arms to catch it.
