How does the structure of a neuron relate to its function?
It is a one-way path of information transport, axons can be long to cover long distances

True or False:
Epithelial cells are vascular
False
True or False:
Epithelial cells can regenerate themselves?
True
True or False:
Endocrine glands are glands that secrete products directly into the bloodstream without a duct
True
True or False:
Goblet cells are found interspersed between single columnar cells and secrete a mucous
True
True or False:
Pseudostratified cells are located in your bladder so it can stretch
False
What is the surface of an epithelial cell that is exposed to the body exterior or inside a cavity called?
Apical surface
Why is our skin made of up stratified squamous?
Many layers offer protection
What is the difference between simple and stratified cells?
Simple is one layer and stratified is multiple
Why would we find simple squamous cells in the lungs?
Single layer of flat cells allows the most exchnage
Why wouldn’t we want transitional cells in our veins?
Transitional cells stretch and if our veins stretch our blood will never make it back from our lower half
Connective tissues vary in blood supply. What is the other characteristic of all connective tissue?
All connective tissues have an extracellular matrix that aids in its function
Name three functions of connective tissue; include an example of where it happens
- Structural framework/protection - skull ribs
- Fat storage - adipose tissue
- fluid/transport - blood
- protection - cartilage
