Q

What is the end part of a long bone called?

A

Epiphyses

19
Q

What is the “spongy” bone in the middle of the bone cavity, with porous areas, called?

A

Cancellous bone

20
Q

What are short bones?

A

Intended for strength and compactness, providing stability and support but limited movement.

21
Q

What is the thin, dense layer in short bones called which covers the cancellous tissue?

A

periosteum

22
Q

What are some examples of short bones?

A

tarsals and carpals

23
Q

What are the structure of flat bones?

A

Broad, flat plates made up of two thin layers of compact tissue with cancellous bone in between.

24
Q

What is the function of flat bones?

A

Protection and provision for muscular attachment

25
Q

What are some examples of flat bones?

A

cranium, scapula, sternum, ribs, ilium

26
Q

What is the function of Irregular bones?

A

Odd-shaped bones which function as a point of attachment for various muscle as well as protection for the nervous system?

27
Q

What is the structure of irregular bones?

A

Like long bones they contain a central cavity of cancellous bone. The outside layers are thin and compact bone

28
Q

What are some examples of Irregular bones?

A

vertebrae, sacrum, coccyx, mandible, hyoid

29
Q

What are Sesamoid bones?

A

Found where tendon passes over a joint; embedded in tendons, increasing mechanical advantage and protecting tendons from flattening in the joint.

30
Q

What are some examples of sesamoid bones?

A

joint bones in hands, knee and feet

31
Q

How many vertebrae does the adult spine contain?

A

24 plus the sacrum and coccyx

32
Q

What are 4 parts of the spine?

A

Cervical, Thoracic, Lumbar, Sacral

33
Q

What does the Cervical spine do?

A

Protects nerves coming from brain to the body

34
Q

How many vertebrae does the Cervical spine consist of?

A

7 (C1-C7)

35
Q

What does the Thoracic spine do?

A

Provides firm attachment of rib cage, protecting vital organs. Little mobility for structural support.

36
Q

How many vertebrae does the Thoracic spine consist of?

A

12 (T1-T12)

37
Q

What does the Lumbar spine do?

A

Provides mobility and structural support of the torso

38
Q

How many vertebrae does the Lumbar spine have?

A

5 (L1-L5)

39
Q

What does the Sacral Region do?

A

Connects the spine to the lower half of the body; Fused portion that forms center of pelvis/supports back wall of pelvis.

40
Q

What is the coccyx?

A

End point of attachment for various ligament, tendons and muscles; serves to distribute weight when sitting

41
Q

What is the Ilium?

A

Upper most pelvic bone in two divisible parts. Connects to sacrum anat sacroiliac joint.

42
Q

What is the Ischium?

A

Below the Ilium and behind the pubis. Strongest of the hip bones.

43
Q

What is the Pubis?

A

Where the left and right hip bones join.
