Skeletal and Muscular System

The scapula is the shoulder blade, which is a flat, triangular bone on the back that resembles a wing. The clavicle is the collarbone, and the hyoid is in the neck.

The joint at the base of the thumb is a saddle joint, which allows for a wide range of movement including opposition. The other names are not standard anatomical terms for this joint.

The patella is the scientific name for the kneecap. The other options are misspellings.

The pelvis is the large bony structure at the base of the spine that forms the hip. The other bones are part of the spine or leg.

Phalanges are the bones of the fingers and toes. Digits refers to the fingers/toes themselves, and metacarpals are in the palm of the hand.

The humerus is the long bone of the upper arm. The radius and ulna are in the forearm, and carpals are in the wrist.

The femur is the thigh bone and is the longest and strongest bone in the human body. The tibia and fibula are in the lower leg.

The clavicle (collarbone) is frequently broken due to its position and relatively thin structure, often occurring during falls or sports injuries.

The wrist contains 8 small bones called carpals, arranged in two rows for flexibility. Note the spelling - options A and B contain errors (tarpals should be tarsals, metatarpals should be metatarsals). Metacarpals are the hand bones between wrist and fingers.

The coccyx is the small triangular bone at the base of the spinal column, commonly known as the tailbone. The sacrum is just above it.

A joint is the anatomical location where two or more bones meet, allowing for movement. Ligaments connect bone to bone, and tendons connect muscle to bone.

The skull is the bony structure that encases and protects the brain. The mandible is just the lower jaw part of the skull.

Bones provide the structural framework for the body and protect vital organs (like the skull protecting the brain and ribs protecting the heart/lungs).

The skeleton is the complete system of bones that supports the body. The other options are individual bones or tissues.

Cartilage is a firm, flexible connective tissue found in areas like the nose, ears, and joints. It provides support while allowing for some movement.
