depressions and openings purpose?
- Form joints
- Allow passage of soft tissue
processes purpose?
- Help to form joints
- Serve as attachment sites for connective tissue
5 different types of depressions and openings?
- Foramen
- Notch
- Meatus
- Fossa
- Sulcus
Foramen
Opening through which blood vessels, nerves, or ligaments pass
Notch
Indentation at bone’s edge
Meatus
Enters, but does not pass through structure
Fossa
Shallow depression
Sulcus
Furrow along a bone surface that accommodates a blood vessel, nerve, or tendon
Three processes that form joints
- Condyle
- Facet
- Head
Condyle (process that forms joints)
Large, round protuberance at the end of a bone
Facet (process that forms joints)
Smooth flat articular surface
Head (process that forms joints)
Rounded articular projection supported on the neck of a bone (i.e. head of the femur)
Six processes that form attachment points
- Crest
- Epicondyle
- Spinous process
- Trochanter
- Tubercle
- Tuberosity
Crest (process that forms attachment point)
Prominent ridge or elongated projection (i.e. iliac crest of hip bone)
Epicondyle (process that forms attachment point)
Projection above a condyle (i.e. medial epicondyle of elbow)
Spinous process (process that forms attachment point)
Sharp, slender projection (i.e. S.P. of vertebra)
Trochanter (process that forms attachment point)
Very large projection (i.e. greater trochanter of femur)
Tubercle (process that forms attachment point)
Small, rounded projection (i.e greater tubercle of the humerus)
Tuberosity (process that forms attachment point)
Large, rounded, usually roughened projection (i.e. ischial)
4 Important muscular terms
- Origin
- Insertion
- Innervation
- Action
Origin (important muscular term)
Placement of muscle attachment for the stationary bone
Insertion (important muscular term)
Placement of the muscle attachment for the bone it moves
Innervation (important muscular term)
The nervous supply to a muscle
Action (important muscular term)
The motion the muscle creates
