| Hard but flexible living structure that provides support for the body and protection for vital organs. | Bones |
| Disruption or "coming apart" of a joint | Dislocation |
| Extremity injury in which the skin has been broken or torn through from the inside by an injured bone or from the outside by something that has caused a penetrating wound associated injury to the bone. | Open extremity injury |
| Special splint that applies constant pull along the length of the leg to help stabilize the fractured femur and reduce muscle spasms | Traction splint |
| Grating sensation of sound made when broken end rub together | Crepitus |
| Bands of connective tissue that bind muscle to bones | Tendons |
| Any break in a bone | Fracture |
| Portion of the skeleton that includes the clavicles, scapulae, arms, wrists, hands, pelvis, thighs, legs, ankles, and feet | Extremities |
| Connective tissue that covers the outside of the bone ends acts as a surface for articulation allowing for smooth movement at joints | Cartilage |
| Muscle injury caused by overstretching or overexertion of the muscle | Strain |
| Process of applying tension to straighten and realign a fractured limb before splinting | Manual traction |
| Places where bones articulate, or meet | Joints |
| Stretching and tearing of ligaments | Sprain |
| Injury to an extremity in which the skin is not broken | Closed extremity injury |
| Connective tissue that supports joints by attaching the bone ends and allowing for a stable range of motion | Ligaments |
| Pairs of nerves that enter and exit the spinal cord between the vertebrae, twelve pairs of cranial nerves that travel between the brain and organs without passing through the spinal cord, and all of the body's other motor and sensory nerves | Peripheral nervous system |
| Mild closed head injury without detectable damage to the brain | Concussion |
| Body system that is divided into two subsystems and that provides overall control of thought, sensation, and the voluntary and involuntary motor functions of the body | Nervous system |
| Cheek bone; also called the zygomatic bone | Malar |
| Bony bump on a vertebra that you can feel on a person's back | Spinous process |
| Bones of the spinal column | Vertebrae |
| Movable joint formed between the mandible and the temporal bones: also called the TM joint | Temporomandibular joint |
| Bony structure making up the forehead, top, back and upper sides of the skull | Cranium |
| Fluid that surrounds the brain and spinal cord | Cerebrospinal fluid (CSF) |
| Bruised brain caused when the force of a blow to the head is great enough to rupture blood vessels | Contusion |
| Brain and the spinal cord | Central nervous system |
| Bones that form part of the sides of the skull and floor of the cranial cavity | Temporal bones |
| Bones that form the upper third, or bridge, of the nose | Nasal bones |
| Bony structures, or sockets, around the eyes | Orbits |
| Nervous system that consists of nerves that control involuntary functions such as the heartbeat and breathing | Autonomic nervous system |
