-
Fissure
- Narrow slit between adjacent parts of bones through which blood vessels or nerves pass
- ex.superior orbital fissure of the sphenoid bone
-
Foramen
- Opening through which blood vessels, nerves, or ligaments pass
-
Fossa
- Shallow depression
- ex. coronoid fossa of the humerus
-
sulcus
- furrow along a bone surface that accommodates a blood vessel, nerve, or tendon
- ex. intertubercular sulcus (groove) of the humerus
-
meatus
- tubelike opening
- ex. external auditory meatus of the temporal bone
-
Processes
projections or outgrowths on bone that form joints or attachment points for connective tissue, such as ligaments and tendons.
-
condyle
- process
- large, round protuberance at the end of a bone
- ex. lateral condyle of the femur
-
facet
- process
- smooth flat articular (relating to joints) surface
- ex. superior articular facet of a vertebra
-
head
- process
- rounded articular (joints) projection supported on the neck (constricted portion) of a bone
- ex. Head of the femur
-
crest
- process that forms point for connective tissue
- prominent ridge or elongated projection
- ex. iliac crest of the hip bone
-
epicondyle
- process that forms attachment points for connective tissue
- epi = above
- projection from a condyle
- ex. medial epicondyle of the humerus
-
line (linea)
- process that forms attachment points for connective tissue
- long, narrow ridge or border (less prominent than a crest)
- ex linea aspera of the femur
-
spinous process
- process that forms attachment point for connective tissue
- sharp, slender projection
- spinous process of a vertebra
-
trochanter
- process that forms attachment point for connective tissue
- very large projection
-
tubercle
- process that forms attachment point for connective tissue
- small, rounded projection
-
tuberosity
- process that forms attachment point for connective tissue
- large, rounded, usually roughened projection
