(41 cards)
How many categories of tissues?
4
- tightly packed
- all have polarity
- arranged in sheets
- a vascularity (no blood vessels)
Epithelial
What are microvili?
Cell membrane that is folded into ridges to increase surface area.
What are cilia?
Tall thin hair like projections, go with the flow
How many layers does simple tissue have?
1 later
Stratified tissues
2 or more layers
Squamous
Flat
Cubodial
Cube
Columnar
Long as they are wide
Type of tissue:
- 1 layer of flat cells
- found in the alveoli of lungs
- purpose is diffusion ( to allow things to pass)
Simple Squamous
Type of tissue:
- 2 or more
- function: to protect
- location: surface of skin
Stratified Squamous Epithelium
Type of tissue:
- 1 layer of Column cells
- function: secretion and absorption
- location: entire digestive tract
Simple columnar epithelium
Type of tissue:
- 1 layer of cube cells
- found in glands
- function: secretion
Simple cuboidal epithelium
Type of tissue:
- 1 layer but looks like multiple layers with uneven columnar cells
- function: secrete and move mucous
- location: respiratory tract
Pseudostratified Ciliated Columnar Epithelium
Name the tissue:
- many layers w/ many cells
- function: to stretch
- location: lining the bladder
Transitional Epithelium
Are glands made up of Epithelial tissue?
Yes
What is the simplest gland?
Goblet cell
What are the two types of glands?
Exocrine and endocrine
- cells are spread apart
- lots of intercellular space
- has matrix
- can contain proteins and fibers
Connective tissue
What are the 3 types of fibers?
Collagen, Recticular, elastic
Collagen fiber:
Strong and big, rope like
Reticular fiber
Soft and interwoven
Elastic fiber
Stretch and recoil (bounce back)
