Fissure

A narrow opening or groove in a bone, typically allowing the passage of nerves and blood vessels.

Sinus

Condyle

A rounded knob on a bone that articulates with another bone, commonly found at joints such as the knee and elbow.

Epicondyle

A protuberance above a condyle on a bone, providing surfaces for muscle and ligament attachment.

Tubercle

A small, rounded projection or protuberance on a bone, usually serving as an attachment point for tendons and muscles.

Tuberosity

Large rounded, and often rough area that serves as a place to connect to muscles and tendons

Crest

Narrow ridgelike projection

Facet

Small nearly flat surface

Fontanel

Soft spot, membrane connecting cranial bones often in newborns

Foramen

Small hole

Fossa

Deep pit or depression

Spine

Thornlike thin projection
