Set of vocabulary flashcards based on the Bone Terminology for the Skeletal System, covering essential terms and their definitions.

Axial Skeleton

made up of the bones in your head, neck, back and chest.

Appendicular Skeleton

includes the bones of the shoulder girdle, the upper limbs, the pelvic girdle, and the lower limbs

Depression

A depression or hollow in a bone

Fossa

a shallow ditch, groove, or depression, typically found in a bone, serving as a space for organs, muscles, or blood vessels,

Fovea

small depression in the retina's macula, specialized for sharp, detailed central vision and densely packed with cone photoreceptors.

Sulcus

a shallow groove, furrow, or depression,

Notch

a V-shaped or U-shaped indentation, gap, or hollow along the edge of a bone or other structure, often serving as a passage for nerves/vessels or to allow articulation with another bone,

Foramen

a hole in a bone or a passage for nerves, blood vessels, and other tissues.

Meatus

a natural body opening or canal.

Sinus

Tubular passage in the body.

Canal

a narrow, tubular channel or passageway within the body that allows structures like nerves, vessels, or fluids to pass through

Fissure

narrow groove, crack, or deep cleft,

Suture

a type of fibrous joint that rigidly connects bones in the skull

Condyle

a smooth, rounded prominence at the end of a bone that forms a joint with another bone,

Facet

a small, smooth, flat surface on a bone

Head

a prominent, rounded bony extension, usually at the end of a long bone, that forms part of a joint,

Articulation

the connection point where two or more bones meet, allowing for varying degrees of movement, from freely movable (like the shoulder) to immovable (like skull sutures)

Tuberosity

Bony prominence on the upper part of the femur (thigh bone) that serves as a crucial attachment site for muscles.

Crest

ridge, elongated prominence, or raised border, usually on a bone, that serves as an attachment point for muscles, tendons, or ligaments.

Spine

The column of bones called vertebrae that runs from the base of the skull to the tailbone.

Process

A projection or outgrowth of tissue from a larger body, most often a bone.

Epicondyle

A rounded, bony bump on the end of a bone that serves as an attachment point for muscles and ligaments, playing a key role in joint stability and movement.

Line

A linear ridge on a bone or an imaginary line on the body's surface used as a reference for surgical or clinical purposes.

Ramus

A projection or branch of a bone, most notably seen in the mandible (lower jaw) and the ischium (part of the pelvis).

Trochlea

A pulley-shaped articular surface on the distal humerus that connects with the ulna to form the elbow joint.

Angle

A geometrical measurement of the space between two intersecting lines or planes, used to describe the orientation, shape, and movement of body parts.

Anterior

The front or forward part of the body.

Apex

The pointed or rounded tip of a structure.

Arch

A curved, bow-like structure.

Articular

A joint, which is the point where two or more bones meet.

Body

A prominence, projection, or raised area on a bodily part, especially a bone.

Concha

The complex region connecting the head to the torso.

Eminence

A V-shaped indentation or depression on the edge or surface of a bone or other structure.

Notch

An opening with two main anatomical locations: one in the heart and one in the skull.
