LAB 2 Flashcards
(32 cards)
Group of cells that have a similar function or specilization wthin an organism
Tissue
Four types of animal tissue
- Epithelial Tissue
- Connective TIssue
- Muscle Tissue
- Nervous Tissue
Tissues form that is the protective covering and inner linings of the body and organs
Epithelial Tissue
Epithelial tissue that is made of tightly packed cells supported by an underlying ____
Basement membrane
Three shapes of the epithelial cell
- Squamous
- Cuboidal
- Columnar
Flat, polyhedral cells with a nucleus at the center
Squamous
Cells with almost equal height from width with a nucleus at the center
Cuboidal
Cells which are taller than wide with a nucleus at the lower region
Columnar
cells are only in one layer
Simple
Cells are stacked in more than one layer
Stratified
Cells appear to have more than once layer, but actually is just one layer with different-sized cells overlapping each other
Pseudostratified
Tissue that supports and bind other organs and tissues together
Develops from mesoderm
Connective tissue
It has less cells (called ____ ), and has more and fluid-like or gel-like solution called the ___
Extracellular matrix
Different types of connective tissues
- Dense connective tissue
- Loose connective tissue
Mas more fibers and less extracellular matrix
Fibers are arranged tightly together, making connective tissue thick
Dense connective tissue
Fibers are arranged in random patterns
Dense irregular CT
FIbers are arranged in regular pattern
Denses regular CT
Special type of dense connective tissue
Bone
Mas more extracellular matrix than fibers
The most widely distributed CT
Loose connective tissue
Special type of loose connective tissue
Blood
Type of loose connective tissue which helps insulate the body
Fat (adipose)
Adipose tissue
Tissue that helps in movement and locomotion, supports bones and other structures
Muscle tissue
Responsible for the movement of your intestines
Peristalsis
Made up of cells that are elongated and spindle-shaped
Myocyte
