100

This is the smallest unit of life.

What is a cell?

100

The type of bone cell that breaks down bone tissue.

What is an osteoclast?

100

The main muscle of breathing.

What is the diaphragm?

100

The basic structural and functional unit of the nervous system.

What is a neuron?

100

This anatomical term means “closer to the point of attachment” on a limb.

What is proximal?

100

This rotator cuff muscle originates on the infraspinous fossa and inserts on the greater tubercle of the humerus.

What is the infraspinatus?

200

The body system responsible for transporting nutrients and gases.

What is the circulatory system?

200

The bone that forms the forehead.

What is the frontal bone?

200

This quadriceps muscle also crosses the hip joint.

What is the rectus femoris?

200

This system includes the brain and spinal cord.

What is the central nervous system?

200

This dense irregular connective tissue layer anchors the skin to underlying structures.

What is the deep fascia (or hypodermis)?

200

This muscle originates from the coracoid process and inserts halfway down the medial humerus.

What is the coracobrachialis?

300

This term means “toward the front of the body.”

What is anterior (or ventral)?

300

The part of a long bone that contains red marrow in children.

What is the epiphysis?

300

The “rotator cuff” includes this muscle that initiates abduction.

What is the supraspinatus?

300

This part of the neuron receives signals from other neurons.

What is a dendrite?

300

This type of cartilage covers the ends of long bones and reduces friction in joints.

What is articular cartilage (hyaline cartilage)?

300

This small muscle originates on the spinous processes of C7–T1 and inserts at the root of the spine of the scapula.

What is the rhomboid minor?

400

The cavity that contains the lungs and heart.

What is the thoracic cavity?

400

This bone forms the posterior part of the hard palate.

What is the palatine bone?

400

This deep arm flexor lies beneath the biceps brachii.

What is the brachialis?

400

This part of the brain controls balance and coordination.

What is the cerebellum?

400

The bone landmark called the olecranon is found on this bone.

What is the ulna?

400

These upper back muscle fibers originate on the occipital bone and nuchal ligament, and insert on the lateral third of the clavicle.

What are the upper fibers of the trapezius?

500

This plane divides the body into equal right and left halves.

What is the midsagittal plane?

500

These two bony landmarks articulate to form the atlanto-occipital joint.

What are the occipital condyles and the atlas (C1)?

500

This is the name of the connective tissue layer that surrounds a fascicle.

What is the perimysium?

500

What is the tiny space where a message passes from one neuron to another?

What is a synapse?

500

This type of epithelial membrane lines cavities that open to the outside, like the digestive or respiratory tract.

What is a mucous membrane?

500

This deep rotator cuff muscle originates on the lateral border of the scapula and inserts on the greater tubercle of the humerus.

What is the teres minor?

700

This tissue lines the digestive tract and absorbs nutrients.

What is Epithelial 

700

This type of ossification forms most flat bones of the skull.

What is intramembranous ossification?

700

This type of contraction occurs when the muscle lengthens while producing force.

What is an eccentric contraction?

700

What part of the neuron carries the signal away from the cell body?

What is the axon?

700

This anatomical structure stores calcium and releases it during muscle contraction.

What is the sarcoplasmic reticulum?

700

This powerful forearm extensor originates from the lateral supracondylar ridge and inserts on the base of the 2nd metacarpal.

What is the extensor carpi radialis longus?
