17
Q

Dense Regular Connective Tissue

A
  • contains fibroblasts and collagen fibers that run parallel to each other
  • enhances tensile strength and resistance to stretching
  • make up tendons and ligaments
  • some have elastin fibers: allows ligaments to return to original length
18
Q

Supportive connective tissue

A
  • include bone and cartilage
  • provide structure, strength and protection
  • contain some cells and fibers
  • maintain posture
19
Q

Bone

A
  • Matrix is rigid and “calcified”
  • hardest connective tissue
  • contains mostly collagen
  • highly vascularized: recover from injuries faster
  • contain osteocytes
20
Q

Cartilage

A
  • firm matrix produced by chondroblasts
  • embedded in matrix are chondrocytes, in space called lacunae
  • dense irregular tissue (perichondrium) surround cartilage
  • avascular: nutrients need to diffuse into matrix
  • slow healing
21
Q

Types of Cartilage

A
  • hyaline cartilage
  • Fibrocartilage
  • Elastic Cartilage
22
Q

Hyaline Cartilage

A
  • most common cartilage
  • short, dispersed collagen fibers
  • appear clear under microscope
  • surface is smooth
  • found in ribcage and nose
  • makes up template of embryonic skeleton and epiphyseal plate
23
Q

Function of hyaline cartilage

A
  • provides support
  • some flexibility
  • covers bones to form moveable joints
24
Q

Fibrocartilage

A
  • tough bcos it contains thick bundles of collagen fibers

- found in knee joint, pubic symphysis, and intervertebral discs

25
Q

Function of fibrocartilage

A
  • provides some compressibility

- absorb pressure

26
Q

Elastic Cartilage

A
  • contains elastin and collagen fibers

- found in external ear (epiglottis)

27
Q

Functions of Elastic Cartilage

A
  • provides firm but elastic support

- cartilage can return to its original shape

28
Q

Function of bone

A
  • provides protection
  • supports body
  • stores calcium
  • provides scaffolding and lever systems for movement
29
Q

Types of bone

A
  • compact: denser, stronger

- spongy: lighter, supportive

30
Q

Fluid Connective tissue

A
  • Lymph and blood

- watery matric w/ salts, nutrients, and dissolved proteins

31
Q

Blood

A
  • contains erythrocytes, leukocytes, and platelets
  • contribute to transportation of materials
  • contributes to bodys ability to repond to injury
32
Q

Lymph

A
  • liquid matrix and leukocytes
  • drains into blood vessels to deliver molecules to blood
  • includes absorbed fats
33
Q

collagen fibers

A
  • provides support

- tensile strength

34
Q

elastic fibers

A
  • thin
  • contains elastin
  • to stretch and recoil
35
Q

reticular fibers

A
  • short, fine
  • made of different types of collagen
  • connects to other fibers
  • surrounds blood vessels
  • supports tissue of organs
  • found where connective tissue is next to other tissues
36
Q

immature cells

A
  • all the cells that end in “- blast”
  • miotic
  • secrete the ground substance and matrix
37
Q

mature cells

A
  • cells that end in “- cyte”

- maintain matrix health

38
Q

Chondrocytes

A
  • in cartilage
  • mature
  • small groups in lacunae
39
Q

chondroblasts

A
  • in cartilage
  • immature
  • produce new matrix until skeleton stops forming
40
Q

fibroblasts

A
  • in connective tissues
  • maintains matrix
  • synthesizes collagen
41
Q

Osteocytes

A
  • in bone
  • in lacunae within matrix
  • mature
42
Q

osteoblast

A
  • in bone
  • immature
  • organic part of matrix
