Epithelial, Connective, Muscle, and Nervous tissue
The plasma membrane is made of this substance
What is a phospholipid bi-layer?
The study of skin
What is dermatology?
A large increase in the number of cell divisions; normally seen as a sign of disease.
What is hyperplasia?
When a cell divides by mitosis, how many daughter cells are produced?
Two
A single layer of flat cells, with a centrally located nucleus.
What is simple squamous epithelium?
Peroxisomes are helped formed by this organelle
What is the Rough Endoplamic Reticulum?
The type of epithelial tissue that is the outermost layer of our skin
What is stratified squamous keratinized epithelium?
Programmed cell death
What is apoptosis?
In what phase of cell division does the nuclear membrane reappear?
Telophase
This type of epithelia lines most of the upper respiratory tract.
What is psuedostratified columnar epithelium?
The site of lipid (steroid) synthesis
