Check what you understood with a short quiz.

Separate the axial skeleton from the appendicular skeleton. Identify how the skull, spine, ribs, limb bones, shoulder girdle, and pelvic girdle create the frame for movement.

Use what you learned in the previous lesson to solve real-world problems.

Find the pelvis, femur, patella, tibia, fibula, and main foot bones on a moving body. Use these landmarks to describe squats, lunges, running, and jumping more clearly.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Find the clavicle, scapula, humerus, radius, ulna, and hand bones during pushing, pulling, throwing, and carrying. Recognize how the shoulder blade and arm bones move together.

Use what you learned in the previous lesson to solve real-world problems.

Locate the vertebrae, ribs, sternum, and pelvis as the main support structures of the trunk. Reason through how the spine and rib cage help posture, breathing, and load transfer.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Recognize cartilage, ligaments, joint capsules, synovial fluid, and tendons around a joint. Distinguish structures that cushion, stabilize, lubricate, and connect muscle to bone.

Use what you learned in the previous lesson to solve real-world problems.

Match common joint shapes to the movements they allow. Compare hinge, ball-and-socket, pivot, saddle, condyloid, and gliding joints using examples like the knee, hip, neck, and wrist.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Use sagittal, frontal, and transverse planes to describe where a movement travels. Pair each plane with its typical axis so terms like rotation and side bending make spatial sense.

Use what you learned in the previous lesson to solve real-world problems.

Describe flexion, extension, and hyperextension in the sagittal plane. Apply the same idea to the hip, knee, elbow, spine, and shoulder during common exercises.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Use dorsiflexion and plantar flexion to describe ankle motion. Connect those terms to walking, running, jumping, calf raises, and landing mechanics.

Use what you learned in the previous lesson to solve real-world problems.

Describe abduction, adduction, and lateral flexion in the frontal plane. Use these terms for jumping jacks, side lunges, shoulder raises, and side bends.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Use inversion, eversion, elevation, depression, protraction, and retraction for smaller but important motions. Apply them to the foot, shoulder blades, and shoulder girdle during exercise.

Use what you learned in the previous lesson to solve real-world problems.

Describe rotation in the transverse plane, including internal and external rotation. Recognize related terms like pronation, supination, and horizontal abduction or adduction.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Use origin, insertion, and line of pull to connect a muscle’s location to its action. Predict why a muscle can move one joint in one direction but not another.

Use what you learned in the previous lesson to solve real-world problems.

Identify agonists, antagonists, synergists, and stabilizers in a movement. Use a biceps curl, squat, or plank to see how muscles can move, oppose, assist, or hold position.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Locate the gluteals, hip flexors, adductors, quadriceps, hamstrings, calves, and tibialis anterior. Connect each group to the hip, knee, or ankle motions it most often helps create.

Use what you learned in the previous lesson to solve real-world problems.

Locate the rectus abdominis, obliques, transverse abdominis, erector spinae, and diaphragm. Connect these muscles to trunk motion, posture, bracing, and breathing during exercise.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Locate the pectorals, latissimus dorsi, trapezius, deltoids, rotator cuff, biceps, and triceps. Connect each group to pushing, pulling, lifting, carrying, and shoulder control.

Use what you learned in the previous lesson to solve real-world problems.

Trace air from the nose or mouth to the lungs and blood from the heart through major vessels. Recognize the heart, lungs, arteries, veins, and capillaries as the key transport map for exercise.

Use what you learned in the previous lesson to solve real-world problems.

Check what you understood with a short quiz.

Locate the brain, spinal cord, peripheral nerves, and autonomic nerves in the exercise map. Reason through how movement commands, sensation, balance, and automatic heart-rate changes depend on this network.

Use what you learned in the previous lesson to solve real-world problems.

Locate the skin, liver, kidneys, digestive tract, pancreas, and adrenal glands as exercise-support organs. Connect them to heat loss, fluid balance, fuel handling, and stress signaling without diving into cell chemistry.
