This division of the nervous system includes the brain and spinal cord.

What is the Central Nervous System? 

100

This muscle type is voluntary, striated, and attached to bones.

What is skeletal muscle?

100

This type of joint allows free movement and includes the knee and shoulder.

What is a synovial joint?

100

This tissue type covers body surfaces and lines organs and cavities.

What is epithelial tissue?

100

This movement increases the angle of a joint.

What is extension?

200

This part of the nervous system connects the CNS to the rest of the body and includes nerves.

What is the Peripheral Nervous System? 

200

This muscle type is involuntary and found in the walls of organs such as the stomach and intestines.

What is smooth muscle?

200

This joint allows movement in only one plane, like the elbow or knee.

What is a hinge joint?

200

This tissue type supports, binds, and protects body structures.

What is connective tissue?

200

This movement decreases the angle of a joint.

What is flexion?

300

This lobe of the brain is primarily responsible for vision.

What is the occipital lobe?

300

This structure is the basic functional unit of a muscle fiber.

What is a sarcomere?

300

These structures connect bone to bone and stabilize joints.

What are ligaments?

300

This directional term means “toward the midline of the body.”

What is medial?

300

This movement involves lifting a body part upward, such as the shoulders.

What is elevation?

400

This cranial nerve is responsible for hearing and balance.

What is the vestibulocochlear nerve (VIII)?

400

This ion is released from the sarcoplasmic reticulum and allows actin and myosin to interact.

What is calcium (Ca²⁺)?

400

This type of ligament injury commonly occurs in the knee due to twisting motions.

What is an ACL tear?

400

This directional term describes a structure that is farther from the point of attachment.

What is distal?

400

This movement describes moving a limb in a circular motion.

What is circumduction?

500

Explain how damage to the frontal lobe would affect behavior and cognitive function.

What is impaired decision-making, personality changes, and loss of voluntary motor control?

500

Summarize two of the muscle rules. 

  1. Attachments & Joints: Muscles must have at least two attachments (origin and insertion) and cross at least one joint.
  2. Pull, Don't Push: Muscles always contract (pull) and get shorter, never push.
  3. Origin & Insertion: The attachment that stays still is the origin; the one that moves is the insertion.
  4. Flexors & Extensors: Flexors decrease joint angles, while extensors increase them (relative to ventral surfaces).
  5. Opposing Pairs: Muscles work in antagonistic pairs (e.g., biceps/triceps).
  6. Fibers Show Direction: Muscle striations (fibers) point in the direction of the pull. 
500

Compare the roles of osteoblasts and osteoclasts in bone remodeling.

What are osteoblasts building bone and osteoclasts breaking down bone?

500

Use proper directional terms to describe the relationship between the skin and skeletal muscles.

What is that the skin is superficial to skeletal muscles, and muscles are deep to the skin?

500

Explain how muscles, bones, and joints work together to produce movement at a synovial joint.

What is muscles contracting to pull on bones across joints, producing movement while ligaments stabilize the joint?
