1

Connective Tissue Proper: Loose (Areolar)

Gel-like matrix with all three connective tissue
fibers, Fibroblasts, macrophages, mast cells, and some white blood cell, Wraps and cushions organs, Widely distributed throughout the body

2

Connective Tissue Proper: Loose (Adipose)

Matrix similar to areolar connective tissue with
closely packed adipocytes, Reserves food stores, insulates against heat loss, and supports and protects, Found under skin, around kidneys, within abdomen, and in breasts, Local fat deposits serve nutrient needs of highly active organs

3

Connective Tissue Proper: Loose (Reticular)

Loose ground substance with reticular fibers, Reticular cells lie in a fiber network, Forms a soft internal skeleton, or stroma, that supports other cell types, Found in lymph nodes, bone marrow, and the spleen

4

Connective Tissue Proper: Dense Regular

Parallel collagen fibers with a few elastic fibers, Major cell type is fibroblasts, Attaches muscles to bone or to other muscles, and bone to bone, Found in tendons, ligaments, and aponeuroses

5

Tendon

muscle to bone

6

Ligaments

bone to bone

7

Aponeuroses

soft tissue to soft tissue

8

Connective Tissue Proper: Dense Irregular

Irregularly arranged collagen fibers with some elastic fibers, Major cell type is fibroblasts, Withstands tension in many directions providing structural strength, Found in the dermis, submucosa of the digestive tract, and fibrous organ capsules

9

Connective Tissue: Hyaline Cartilage

Amorphous, firm matrix with imperceptible
network of collagen fibers, Chondrocytes lie in lacunae, Supports, reinforces, cushions, and resists compression, Forms the costal cartilage

10

Connective Tissue: Hyaline Cartilage found in

Found in embryonic skeleton, the end of long bones, nose, trachea, and larynx

11

Connective Tissue: Elastic Cartilage

Similar to hyaline cartilage but with more elastic fibers
Maintains shape and structure while allowing flexibility
Supports external ear (pinna) and the epiglottis

12

Orcein

Stains hyaline cartilage

13

Silver

stains Recticular connective tissue

14

What stains adipose tissue

Sudan Black and Osmium Tetroxide

15

Connective Tissue: Fibrocartilage

Matrix similar to hyaline cartilage but less firm with thick collagen fibers
Provides tensile strength and absorbs compression shock
Found in intervertebral discs, the pubic symphysis, and in discs of the knee joint

16

Connective Tissue: Bone (Osseous Tissue)

Hard, calcified matrix with collagen fibers found in bone
Osteocytes are found in lacunae and are well vascularized
Supports, protects, and provides levers for muscular action
Stores calcium, minerals, and fat
Marrow inside bones is the site of hematopoiesis

17

Isogenous

Same Origin

18

Connective Tissue: Blood

Red and white cells in a fluid matrix (plasma)
Contained within blood vessels
Functions in the transport of respiratory gases, nutrients, and wastes

19

Serum

Without clotting factors

20

Plasma

with clotting factors

21

Never Let Monkey Eat Banana

Neutrophil, Lymphocyte, Monocyte, Eosinophil, Basophil

22

Nervous Tissue

Branched neurons with long cellular processes and support cells
Transmits electrical signals from sensory receptors to effectors
Found in the brain, spinal cord, and peripheral nerves

23

Muscle Tissue: Skeletal

Long, cylindrical, multinucleate cells with obvious striations
Initiates and controls voluntary movement
Found in skeletal muscles that attach to bones or
skin

24

Muscle Tissue: Cardiac

Branching, striated, uninucleate cells interlocking at intercalated discs
Propels blood into the circulation
Found in the walls of the heart
Involuntary control

25

Muscle Tissue: Smooth

Sheets of spindle-shaped cells with central nuclei that have no striations
Propels substances along internal passageways (i.e., peristalsis)
Found in the walls of hollow organs

26

Primary germ layers

27

Nerve tissue arises from

ectoderm

28

Muscle, connective tissue, endothelium, and mesothelium arise from

mesoderm

29

Epithelial tissues arise from

all three germ layers ectoderm, mesoderm, and endoderm
