17
Q

Functions of connective tissue

A

binding of organs, support, physical protection, immune protection, movement, storage, heat production, transport

18
Q

cells in CT

A

fibroblasts, macrophages, leukocytes, plasma cells, mast cells, adipocytes

19
Q

fibers in CT

A

Collagenous, Reticular, Elastic

20
Q

Loose CT dense irregular

A

found in skin, fibroblast, collagen fibers, scattered and unorganized

21
Q

Dense CT dense regular

A

found in tendons and ligaments, fibroblasts, college, and fibers, highly organized

22
Q

Areolar CT

A

is found in the skin and other parts of the body, use as padding, filled with immune cells

23
Q

Reticular Fibers

A

Fibers found in lymph nodes, constructs for cellular components, architectural in functions

24
Q

Adipose: Adipocytes

A

anywhere on the body, Functions as padding, energy storage, Can become mitotically active – tumor/lipoma
Can become malignant

25
Q

characteristics cartilage

A

Chondroblasts (developing)
Lacunae
Chondrocytes (mature)
Perichondrium

26
Q

Types of Cartilage

A

Hyaline - weakest
Elastic – has elasticity
Fibrocartilage – greatest tensile strength

27
Q

Hyaline Cartilage

A

Example shown is embryonic skeletal template
Cells are in spaces called lacuna
Fewer cells than matrix
Perichondrium surrounds tissue; weakest of cartilages
Here will eventually become bone
Found in ribs, tracheal rings, growth plate of bone

28
Q

Elastic Cartilage

A

Chondrocytes same as hyaline
Elastic fibers found in matrix
Found in ears, tip of nose
Tissue has great elasticity and memory for shape
Perichondrium surrounds the perimeter of tissue

29
Q

Fibrocartilage

A

Chondrocytes like hyaline
Collagen fibers throughout matrix; fibroblasts too
Strongest of cartilages; load bearing, great tensile strength
Found in intervertebral disks, menisci and in TMJ disk
NO perichondrium

30
Q

Bone types

A

Spongy
Compact
Central – Haversian canals
Concentric lamellae

31
Q

Bone compact

A

Osteon
Osteocytes
Canaliculi
Periosteum

32
Q

Blood

A

Plasma
Formed elements
Erythrocytes
eukocytes or white blood cells (WBC’s)

33
Q

Nervous Tissue

A

Neurons
Glial
Communicative

34
Q

Muscular Tissue

A

Skeletal
Cardiac
a. intercalated discs
Smooth

35
Q

Endocrine Glands-Functional Classification

A

Merocrine also called Eccrine
Holocrine
Apocrine

36
Q

Epithelium in Glands

A

37
Q

Membranes

A

a. Cutaneous (skin)

40
Q

Repair

A

A. Regeneration
B. Fibrosis
