A

Sternum&ribs
Skull
Vertebral column

24
Q

What do appendicular bones include?

A

Everything else

  • pelvic girdle
  • pectoral girdle
  • upper/lower limbs
25
Q

What does connective tissue consist of?

A

Cells are similar in different connective tissue in matrix of ground substances & fibers

26
Q

What ground substance in proper connective tissue? In cartilage?

A

Thin gel
Firm gel
Impregnated with inorganic salts in bone

27
Q

What are fibers in connective tissue?

A

Collagen

Elastin

28
Q

Properties of collagen?

A

Tough and resistant to force, fibers are parallel in fiber

29
Q

Properties of elastin?

A

Strong and can be stretched, fiber branch

30
Q

What are two types of connective tissue?

A

Proper: fascia, ligament, tendons
Specialized: cartilage and bone

31
Q

Properties of proper connective tissue?

A

Tough but compliant

32
Q

Properties of specialized connective tissue?

A 
Solid
Resist pull (tension) and pressure (compression)
33
Q

What are two types of proper connective tissue?

A

Loose

Dense or fibrous

34
Q

Does proper connective tissue support? What is it called when it contains lots of fat?

A

No

Adipose tissue

35
Q

What is superficial fascia?

A

Layer immediately under skin where fat stored

36
Q

What dominate in dense/fibrous proper connective tissue? What does it include?

A

Fibers

Deep fascia/ ligament/ tendons

37
Q

What is fascia? Functions?

A

Sheets that envelop body parts

  • Stores water and fat.
  • protection against blow
  • pathway for nerves and blood to enter and exit muscles
38
Q

What does deep fascia blend with?what is medial and lateral fascia called?

A

Periosteum to connect to bone

Septa

39
Q

What is internal fascia function?

A

Connect pleura(thorax) and peritoneum (abdomen) to body wall

40
Q

What differentiates the tissues?

A

The matrix of ground substance and fibers
