Bones Flashcards
Appendicular
Bones within the limbs
Axial
Bones within the body
Heterotropic
Out of place bone (os penis in the dog)
3 ways to classify bones:
Location
Shape
Development
Bone development: Intramembranous ossification
Ossification of fibrous connective tissue (flat skull bones)
Bone development: Endochondral ossification
Ossification of cartilage that is typically in the shape of the bone. Diaphysis is the first location to ossify followed by the epiphyses
Physis
-growth. Region where long bones grow (growth plate)
Epiphysis
Upon the physis (end of bone)
Metaphysis
Beyond the physis (between the physis and diaphysis)
Diaphysis
Between the physis (shaft of the bone)
Cortex
Bark (outside of the bone)
Medullary cavity
Innermost part of the bone
Open physis
Bone is still growing
Closed physis
Bone growth is complete
Condyle
Rounded end (knuckle)
Epicondyle
Upon the condyle (on 2 sides o the condyle)
Trochlea
Pulley wheel (located on the condyle)
Tubercle (tuberosity)
Tuber (bump)- Greater and lesser tubercle and deltoid tuberosity on the humerus.
Fovea (fossa)
pit (ditch)- Radial fossa on the cranial portion of the humerus, elecronon fossa on the caudal portion of the humerus.
Supratrochlear foramen
small hole located above the trochlea of the humerus in the dog (supracondylar foramen in the cat- median nerve and brachial artery pass through this in the cat)
Foramen
Hole, opening or passage way
Acromion
A bony process of the scapula (consists of the hamate process and a supramamate process in the cat)
