B1 Anatomy of Bone Surface Flashcards
What is the purpose of depressions and openings of the bone?
To allow the passage of soft tissue or formation of joints.
What is a fissure?
A narrow slit between adjacent parts of bones through which blood vessels or nerves pass.
Where can a fissure be found?
Superior orbital fissure of sphenoid bone
What is a foramen?
A hole/ opening through which blood vessels, nerves, or ligaments pass.
Where can foramina be found?
Optic foramen of sphenoid boneMental foramen
What is a fossa?
A shallow depression.
Where can fossae be found?
Coronoid fossa of humerus.
What is a sulcus?
A groove along the bone surface that accommodates a blood vessel, nerve, or tendon.
Where can sulci be found?
Intertubercular sulcus of humerus.
What is a meatus
Latin for passageway, a tubelike opening.
Where can a meati be found?
Nasal CavityExternal auditory meatus of temporal bone.
What are processes?
Projections/ outgrowths on bone that form joints/ attachment points for connective tissue.
What is a condyle?
Latin for knuckle, a large, round protuberance with a smooth articular surface at the end of the bone.
Where can condyles be found?
Lateral condyle of femur.
What is a facet?
Smooth, flat, slightly concave or convex articular surface.
Where can facets be found?
Superior articular facet of vertebra-
What is a head?
Usually rounded articular projection supported on neck (constricted portion) of bone.
Where can heads be found?
Head of femur.
What is a crest?
A prominent ridge or elongated projection.
Where can crests be found?
Iliac crest of hip bone.
What is an epicondyle?
A typically roughened projection above condyle.
Where can epicondyles be found?
Medial epicondyle of femur.
What is a line?
A long, narrow ridge or border (less prominent than crest).
Where can lines be found?
Linea aspera of femur.
What is a spinous process?
A sharp, slender projection.
Where can spinous processes be found?
Vertebrae
What is a trochanter?
A very large projection.
Where are trochanters found?
Greater trochanter of femur.
What is a tubercle?
A variably sized rounded projection.
Where are tubercles found?
Greater tubercle of humerus.
What is a tuberosity?
A variably sized projection that has a rough, bumpy surface.
Where are tuberosities found?
Ischial tuberosity of hip bone.
