Anatomy Lecture Tissues

Front 1

Regeneration of Epithelial cells

Back 1

Epithelial cells replace damaged or dead cells. Only cells closest to the basal lamina go through mitosis pushing dead or injured cells to the surface. Dead cells protect the rest of the cell layers.

Front 2

Secretions of epithelial cells

Back 2

Epithelial tissue may contain glands that produce secretion. (not all)

Front 3

Transitional tissue 9function and location)

Back 3

urinary bladder, ureter, urethra. function: stretching for urine.

Front 4

Pseudostratified cilated columnar tissue. location and function

Back 4

Trachea, bronchi. Function: protection with cilia to trap particles and move away mucus

Front 5

Simple Columnar tissue. Location and Function

Back 5

Stomach, large and small intestines. Kidney tubules. Function: protection with movement

Front 6

Simple and stratified Cuboidal. Location and function

Back 6

Thyroid gland, sweat glands, kidney tubules. Function: secretion

Front 7

Stratified Squamous. Location and function

Back 7

Epidermis, Esophagus, anal canal, vagina

Front 8

Simple squamous. Location and function

Back 8

lungs, blood vessels(lining), kindey glomerus. Function: easy transportation

Front 9

Gross Anatomy

Back 9

The structures you are studying are big enough to see with the naked eye.

Front 10

Systems approach

Back 10

Looking at one system at a time.

Front 11

tissue

Back 11

Grouping of cells similar and part of a unit.

Front 12

endocrine glands

Back 12

no excretory duct

Front 13

multicellular glands

Back 13

consist of endocrine and exocrine glands.

Front 14

general epithelial characteristics (5)

Back 14

1. All epithelial tissue has a basal lamina.
2. all epithelial tissue with out blood vessels-avascular.
3. all epithelial tissue regenerates new cells.
4. polarity- difference of structure and function between cells.
5. Some epithelial tissues may contain glands that produce secretion.

Front 15

basal lamina

Back 15

Basal lamina is a foundation for epithelial tissue between the bottom layer of epithelial tissue and connective tissue. Basal lamina keeps things out and coming in. AKA basement membrane= basal lamina + lamina reticularis. Basal lamina is made up of a secretion of protein and carbs from the epithelial cells.

Front 16

Connective tissue cells (5)

Back 16

1. Fibroblast: most common connective tissue cells can become specialized cells. ie, may become osteoblast, changing function based on location.
2. Macrophage cells: Function as phagocytes to get rid of anything in your body no longer wants. ie, dead cells, bacteria.
3. Melanocytes: Produces melanin pigment and can be found in Epithelial tissue.
4. Adipocytes: stores fat
5. Leukocytes: white blood cells, fight infection

Front 17

General characteristics of connective tissue

Back 17

1. cell
2. background material
a. ground substance
b. fibers
3. fiber

Front 18

Connective tissue background material

Back 18

1. Ground substance: geltin-like
2. matrix: ground substance plus other compounds to make it strong. ie., bone, cartilage only use matrix. added compounds of bone consist of hydroxyapatite, and for cartilage is chondrotin sulfates.

Front 19

Types of anatomy that require microscopes

Back 19

-cellular anatomy
-histology (study of tissues)

Front 20

connective tissue fibers

Back 20

fibers are proteins produced by cells.
1. collagen
2. elastin
3. reticular
