This neurotransmitter, often called the "feel-good" chemical, is released during physical activity and helps improve mood.
What is endorphins
The adult human body has this many bones.
These types of joints allow free movement and include hinge and ball-and-socket types.
What are synovial joints
These are the three types of muscle tissue in the body.
What are skeletal, cardiac, and smooth muscle
This overuse injury causes inflammation of a tendon.
What is tendinitis
Regular physical activity reduces the risk of this chronic disease by improving insulin sensitivity.
What is Type 2 diabetes
These are the two main divisions of the skeletal system.
What are axial and appendicular
The shoulder and hip are examples of this type of joint.
What is a ball-and-socket joint
This connective tissue attaches muscle to bone.
What is a tendon
A sprain involves damage to these structures.
What are ligaments
Community-based physical activity programs help reduce this major public health issue.
What is obesity
This type of bone cell is responsible for breaking down and reabsorbing bone tissue.
What is an osteoclast
These strong bands of connective tissue connect bone to bone
What are ligaments
This condition occurs when muscles cannot relax due to lack of ATP, often seen after death.
What is rigor mortis
This os the most common ankle injury, which involves tearing or stretching of ligaments
What is an inversion sprain
This system benefits from exercise through improved cardiac output and lower resting heart rate.
What is the cardiovascular system
The femur is an example of this type of bone, characterized by being longer than it is wide and having a shaft with two ends.
What is a long bone
This type of cartilage covers the ends of bones in synovial joints to reduce friction.
What is articular cartilage
This energy molecule is required for muscle contraction and relaxation.
What is ATP (adenosine triphosphate)
This injury occurs when the kneecap slips out of its normal position.
What is a patellar dislocation
This mental health benefit of exercise helps reduce symptoms of anxiety and depression.
What is stress relief
This mineral is stored in bones and is essential for nerve and muscle function.
What is calcium
Name the three main classifications of joints based on movement.
What are fibrous, cartilaginous, and synovial joints
This theory explains how actin and myosin interact to produce muscle contraction.
What is the sliding filament theory
These tiny cracks in bone often occur from repetitive stress or overtraining.
What are stress fractures
