Skeletal System Fundamentals

Vocabulary-style flashcards defining the components, divisions, and biological functions of the human skeletal system based on lecture notes.

Adult Skeletal System

The skeletal structure of an adult consisting of $206$ bones.

Baby Skeletal System

The skeletal structure of a baby consisting of $272$ to $300$ bones.

Ligaments

Connective tissues that link bone to bone.

Tendon

Connective tissue that links bone to muscle.

Axial Skeleton

One of the two divisions of the skeleton containing the middle structures: the skull and spinal column.

Appendicular Skeleton

One of the two divisions of the skeleton containing the side structures: the limbs and girdles.

Bony Thorax

The part of the axial skeleton composed of the ribs and sternum.

Radius

A bone in the upper limb that connects to the thumb.

Hematopoiesis

The process of blood cell formation occurring within the bones.

Functions of Bones

Body support, protection of soft organs, movement via attached skeletal muscles, storage of minerals ($Ca$ and $P$) and fats, and hematopoiesis.

Pectoral Girdle

A group of bones in the appendicular skeleton consisting of the clavicle and scapula.

Pelvic Girdle

The bones that support the lower limbs in the appendicular skeleton.

Phalanges

The bones that make up the fingers and toes.

Tarsals

The bones located in the ankle region of the foot.

Metacarpals

The bones of the hand located between the carpals and phalanges.

Humerus

The long bone of the upper arm.

Femur

The long bone of the upper leg or thigh.

Patella

The bone commonly known as the kneecap.

Tibia

The larger, medial bone of the lower leg.

Fibula

The thinner, lateral bone of the lower leg.
