Articular Projections
This rounded articular surface forms part of a joint and is often found at the ends of long bones.
What is a Condyle?
This prominent ridge on the bone serves as a major muscle attachment site.
What is a Crest?
This sharp, pointed projection provides attachment for muscles and ligaments.
What is a Spine?
This shallow, basin-like depression in a bone often serves as a point for articulations or to hold structures.
What is a Fossa?
This canal-like passageway is found within bones and allows structures to pass through.
What is a Meatus?
This small, flat articular surface allows for the smooth sliding motion of bones.
What is a facet?
A slightly raised and elongated ridge found on the bone, useful for muscle attachment.
What is a Line?
A projection above a bone's condyle, it provides surfaces for attachment.
What is an Epicondyle?
An elongated groove or trench-like depression on the bone surface.
What is a Sulcus?
This opening permits the passage of blood vessels and nerves through a bone.
What is a Foramen?
The upper rounded part of a bone that fits into a socket, commonly seen in the femur and humerus.
What is a head?
The roughened area on a bone that serves as a site for the attachment of tendons and muscles.
What is a Tuberosity?
Found along the ridge of the bone, this feature can be less prominent than a crest but still offers attachment points.
What is a Line?
A natural opening or cavity in the bone, especially those filled with air and lined with mucous membranes.
What is a Sinus?
This groove on the bone surface allows for the placement of tendons, nerves, or blood vessels.
What is a Sulcus?
This articular surface is round and smooth, forming a joint that allows for rotational movement, such as in the femur.
What is a Head?
A small, rounded projection that serves as a site for muscle and ligament attachment, often found near joints.
What is a Tubercle?
A bony protrusion that serves as a point of muscle attachment, smaller and more delicate than a tuberosity.
What is a Tubercle?
A deep groove or slit between adjacent parts of bones, often providing a pathway for nerves and vessels.
What is a Fissure?
A larger, elongated opening or cleft within a bone, commonly found in the skull.
What is a Fissure?
A smooth, nearly flat surface on a bone that typically forms a gliding joint, seen in vertebrae and small bones of the wrist and ankle.
What is a Facet?
A large, irregular process found on the femur, serving as a key site for muscle attachment.
What is a Trochanter?
This thickened part of the bone is designed for the attachment of large muscle groups, and is generally rough in texture.
What is a Tuberosity?
A small, round depression that allows for the passage of a structure or for articulation with another bone.
What is a Fossa?
This natural cavity in the bone structure can contain air and aid in lightening the bone’s weight.
What is a Sinus?
