Answer 2

Intercondylar fossa

Medial condyle FOSSA lateral condyle
Epicondyle

Question 3

Ulna goes where on humerus?

Small indent on opposite side?

Answer 3

Olecranon fossa

Coronoid fossa

Question 4

Indentation in head of femur?

Answer 4

Fovea capitis

Question 5

Tuberosity?

Answer 5

Elevation of bone

Humerus deltoid tuberosity

Question 6

Long bone growth in length occurs where?

Answer 6

Epiphyseal plate

Question 7

4 major sutures and where are they?

Answer 7

Coronal suture (crown)
Sagittal suture (straight down middle)
Lambdoid suture( (rear of head by occipital)
Squamous suture (by ears)

Question 8

Spongy bone isn’t located where in a long bone?

Answer 8

Diaphysis

Question 9

Appositional bone growth

Answer 9

Osteogenic cells differentiate into osteoblasts that add bone matrix under the PERISTEUM

Osteoclasts remove matrix at inner surface compact bone to enlarge medullar cavity

Question 10

Compact bone functional unit and

Organization

Answer 10

Osteon

Osteocytes (in lacunae) lie b/w lamellae.
Canaliculi connect lacunae with each other and central canal

Central canal contains blood vessels and nerves

Question 11

Spongy bone “struts”

Marrow? For what?

Answer 11

Trabeculae

Red bone marrow fills spongy bone for hematopoiesis

Question 12

Long bone growth steps

Answer 12

Chrondrocytes divide producing new cells.
New cells push old cells towards diaphysis.
These elongate causing lacunae to enlarge
Surrounding matrix calcifies
Eliminates movement of nut and they die
Leaves spaces separated by calcified cartilage
Osteoblasts and osteoclasts move in and transform into spongy bone

Question 13

Lower part that sticks out on humerus?

Answer 13

Capitulum
