|
G1 Phase
|
Cell grows and prepares for mitosis
|
|
|
S Phase
|
Duplication of DNA
|
|
|
G2 Phase
|
More cell growth, synthesis of proteins needed for mitosis, checking of DNA quality
|
|
|
Prophase
|
Chromatin becomes more condenses and chromosomes become visible
|
|
|
Metaphase
|
Chromosomes line up on the equator using the centromere
|
|
|
Anaphase
|
Spindle fibers pull sister chromatids to opposite poles
|
|
|
Telophase
|
Chromosomes are at opposite piles, and they become chromatin again. Nucleolus and nuclear membrane reappear
|
|
|
Glycocalyx
|
A glycoprotein area adjacent to the cell that provides a highly specific biological marker for cell recognition
|
|
|
Integral Proteins
|
Embedded in the phospholipid bilayer
|
|
|
Transmembrane proteins
|
Span entire thickness of the lipid bilayer
|
|
|
Peripheral Proteins
|
Located on the inside or outside of the membrane and many act as enzymes and receptors
|
|
|
Epithelial Tissue
|
Tissue that covers body surfaces, lines body cavities, forms boundaries between different environments, protects, secretes, absorbs, and filters.
|
|
|
Connective Tissue
|
Tissue that supports, protects, and binds tissues together.
|
|
|
Muscle Tissue
|
Tissues that contracts to cause movement
|
|
|
3 Types of Muscle Movement
|
Skeletal, Smooth, and Cardiac
|
|
|
Nervous Tissue
|
Tissue that deals with internal communication, neurons, and glial cells.
|
|
|
Ectoderm
|
External body surface of epithelial tissue
|
|
|
Mesoderm
|
Lining of vascular system, serous membrane and part of the urogenital system.
|
|
|
Endoderm
|
Lining of the digestive and respiratory system
|
|
|
Lamina lucida
|
Portion of the basement membrane that is low density and close to epithelial cells
|
|
|
Lamina densa (basalis)
|
Part of the basement membrane that contains proteoglycans, laminin, fibronectin, and collagen IV
|
|
|
Sub-basal lamina
|
Located in most basement membranes contans reticular fibers and connects the lamina densa to the connective tissue. Responsible for the stretching and recoil of epithelium for distention
|
|
|
Gland
|
Consists of one or more cells that make and secrete a particular products
|
