Tissues Continue

Question 1

Transitional

Answer 1

Multiple layers
Cells change shape
Location:
Urinary bladder

Function:
Change shape and stretch

Question 2

Glandular Epithelium

Answer 2

Endocrine glands: Release substances into the body
Hormones

Exocrine glands: Release substances into the surface
Sweat glands, mucous cells

Question 3

Merocrine glands

Answer 3

The final production of the
product is in the golgi complex

Transported through vesicles
and secreted through exocytosis

Sweat glands
Pancreatic digestive enzymes

Question 4

Apocrine glands

Answer 4

After production, the
product accumulates
in apical end of cell

This end pinches off
and bursts to release
the product

Mammary glands

Question 5

Holocrine Glands

Answer 5

The product accumulates in the
cell

The cell lyses to release the
product

Sebaceous glands

Question 6

Connective Tissue

Answer 6

Functions:
	Binds tissues together (tendons)
	Supports and strengthens other tissues
	   (dermis of skin, membranes)
	Protection of vital organs (skeleton)
	Transport (blood)
	Insulation (fat)
	Energy storage (fat)
	Immune response (white blood cells)

Question 7

The Matrix

Answer 7

Fibers:
Collagen: Strong, resist stretching
Elastic: Form a network, stretch (150%) and recoil
Reticular: Form a network to support cells
Support and strength
Ground substance
The molecules between the cells and the fibers
Fluid, semi-fluid, gelatinous, calcified

Question 8

Loose Connective Tissue

• Areolar connective tissue
• Adipose tissue
• Reticular connective tissue

Answer 8

Fibroblasts, macrophages, mast cells
All three types of fiber, random distribution
Widely distributed, under skin, digestive tract, etc.

Some reticular fibers, adipocytes store fat
Widely distributed in the body

Reticular cells
Reticular fibers form a mesh to support cells
Liver, spleen, kidneys, lymph nodes

Question 9

Areolar Connective Tissue

Adipose Tissue

Answer 9

Location:
 All over body
Function:
 Weak flexible
 binding
Location:
 All over body

Function:
Energy storage

Question 10

Reticular Connective Tissue

Answer 10

Location:
 Lymph node, spleen,
 liver
Function:
 Framework

Question 11

Dense of Connective Tissue
-Dense regular connective tissue

• Dense irregular connective tissue
• Dense regular elastic connective tissue
• Dense irregular elastic connective tissue

Answer 11

Fibroblasts secrete collagen, all fibers parallel
Tendons, ligaments

Fibroblasts secrete collagen, random distribution
Dermis of skin, fascia around muscles

Fibroblasts secrete elastic fibers, all fibers parallel
Vocal cords

Fibroblasts secrete elastic fibers, random distribution
Aorta, lungs

Question 12

Cartilage
-Hyaline cartilage

• Elastic cartilage
• Fibrocartilage

Answer 12

Cells are in lacuna
-Thin, pale collagen fibers (not visible)
Ends of long bones, trachea, growth of skeleton
-Elastic fibers
Ear and nose
-Thick visible collagen fibers
Pubic symphysis, intervertebral discs, miniscus in knee

Question 13

Other connective tissue
-Bone

• Blood
• Lymph

Answer 13

-Osteocytes in lacuna, calcified matrix, collagen fibers
Skeleton

-Plasma and formed elements (cells and platelets)
Liquid matrix in blood vessels

-Clear liquid flows through lymphatic system

Question 14

Muscle tissue

• Skeletal muscle
• Cardiac muscle
• Smooth muscle

Answer 14

-Striated, voluntary, long cells, multinucleated
Muscles that move the skeleton

-Striated, involuntary, branching fibers, influenced
by hormones and autonomic nervous system
Heart muscle, pumps blood

-No striations, involuntary, influenced by hormones
and the autonomic nervous system
Blood vessels, intestine, etc.
