1

What are the effects of thyroid and sex hormones on bone development and growth

Thyroid hormones stimulate replacement of cartilage in the epiphyseal plates of long bones with bone tissue. Sex hormones stimulate ossification of epiphyseal plates and stop bone growth.

2

What are fontanels; what's their significance?

They permit some movement between the bones so that the developing skull is partially compressible and can change shape for birth. Soft spots on babies head

3

Describe a typical vertebrae

Body, Pedicles, laminae, spinous process, vertebral arch, vertebral foramen, transverse process, superior and inferior articulate processes, intervertebral foramina

4

What part of the vertebra is drum shaped and forms the thick anterior portion of the bone that support the weight of head and trunk

Body

5

What part of vertebra projects posteriorly from the body and the forms the sides of the vertebral foramen

Pedicles

6

What part of the vertebra are plates that arise from the Pedicles and fuse in the back

Laminae

7

What forms as a result of the laminae fusing

Spinous process

8

What is the bony arch comprised of Pedicles, laminae and spinous process that forms around the vertebral foramen

Vertebral arch

9

What is the opening that the spinal cord passes through

Vertebral foramen

10

What is the projection from each side between the Pedicles and laminae

Transverse process

11

What project upward and downward from each vertebral arch

Superior and inferior articulate processes

12

What are openings formed by notches on the lower surfaces of the vertebral Pedicles that align with adjacent vertebrae; and provides passengers for spinal nerves

Intervertebral formina

13

What vertebrae have bifid (forked) spinous processes; and the transverse processes have transverse foramina that leases way for arteries into the brain?

Cervical

14

What vertebrae compose the axis of the neck

Seven cervical

15

What cervical vertebrae is the first that supports the head

Atlas

16

What second cervical Vertebra allows the head to turn from side to side

Axis

What vertebrae have long pointed spinous processes sloping downward; facets in the side that articulate with ribs?

Thoracic

18

What vertebrae have large bodies that are short with stubby spinous processes

Lumbar

19

What is the triangular structure at the base of the vertebral column

Sacrum

20

What is the lowest part of the vertebral column

Coccyx

21

What does the thoracic cage include

Ribs, thoracic vertebrae, sternum, costal cartilages that attach ribs to sternum

22

What are the three parts of the sternum

Manubrium, body, xiphoid process

23

What process forms the tip of the shoulder

Acromion

24

What process provides attachments for upper limb and chest muscles

Coracoid

25

What cavity articulates with the head of the arm bone

Glenoid

26

Where does the capitulum of the humerus articulate with the radius?

Elbow

27

What does the trochlea of the humerus join?

Ulna

28

What depression receives a process of the ulna( coronoid process) when the elbow bends

Coronoid fossa

29

What depression receives the olecranon process when the elbow straightens

Olecranon fossa

30

What is the largest most superior portion of the hips bone

Ilium
