NERVOUS
The nervous system is divided into...
CNS and PNS
What two main body systems make up the musculoskeletal system?
The muscular system and the skeletal system.
What system tells muscles when to move?
The nervous system.
What type of movement is controlled by choice?
Voluntary movement.
What does the musculoskeletal system provide for the body?
Structure, strength, and movement.
What does the brain send to control body movements?
Electrical impulses (signals) through motor neurons.
What connects muscles to bones?
Tendons.
What system allows movement to actually happen?
The musculoskeletal system.
What type of movement happens automatically to protect the body?
Reflex actions (involuntary movement).
What does the nervous system provide for the body?
Control, coordination, and communication.
What do sensory neurons do?
They send information from the body to the brain about touch, temperature, pain, and position.
What are the 5 main functions of the musculoskeletal system?
Support, movement, protection, posture, and storage of minerals.
What kind of neurons carry signals from the brain to the muscles?
Motor neurons.
Why is this interrelationship important for athletes?
It improves coordination, speed, balance, and reaction time.
What happens when both systems work together?
The body can move, react, and stay balanced.
What is proprioception?
The body’s ability to sense its position and movement.
What is the role of ligaments in the body?
They connect bones to other bones and stabilize joints.
What kind of neurons send signals back to the brain about body position and balance?
Sensory neurons.
Which muscle is controlled by the nervous system to help you breathe?
The diaphragm.
Why are these systems considered interdependent?
Because one cannot function properly without the other.
How does the nervous system control voluntary and involuntary actions?
Voluntary actions are controlled by conscious brain signals; involuntary actions happen automatically through the spinal cord and brainstem.
How do muscles cause movement in the body?
By contracting and pulling on bones to move joints.
What is the term for the coordination between nerves and muscles that allows movement?
Neuromuscular coordination.
What would happen if the nervous system stopped sending signals to the muscles?
Muscles would stop moving, causing paralysis.
What is three everyday activity that shows the interrelationship between both systems?
Examples: walking, running, writing, or catching a ball.
