Transitional epithelium
What organ system is the ONLY one with transitional epithelium?
Urinary system
Tissue on a slide has two layers of cube-like shapes with centrally located nuclei. What are you observing?
Stratified cuboidal
Epithelial tissues always exhibit polarity (one free side and one attached)
True or false?
True
What happens to epithelial tissue damaged from a paper cut?
Healed by regeneration
What muscle tissue is made of striated, multinucleated cells and acts under voluntary movement?
Skeletal muscle

Holocrine glands
Blood platelets play a role in which of the following?
- fighting infection
- blood clotting

Blood clotting
Epidermis cells of skin need to be held tightly together to form an impermeable barrier. What junctions do this?
Tight junctions
EMC of connective tissues is made up of what?
- protein fibers
- ground substance
- fixed and wandering cells
- lacunae

Protein fibers and ground substance
Define histology
Study of tissues
What are the four major tissue types in the human body?
Epithelial
Connective
Muscle
Nervous
Define/describe epithelial tissue
Tightly packed, no visible ECM, cover and line body surfaces/cavities.
Specialized epithelia form glands
Define/describe connective tissue
Connect tissues to one another, ECM is prominent for most, cells are scattered
They bind, support, and allow transportation
Define/describe muscle tissue
Can generate force by contracting, little ECM between cells.
Types are cardiac, smooth, and skeletal
