Epithelial
Connective
Muscle
Nerve
How do epithelial tissue and connective tissue differ from each other
Epithelial tissue is closely packed cells (forms glands)
Connective tissue is loosely collection embedded in a non living matrix
tissue has a matrix that is rich in collagen fibers

great toe
The hollow area on the anterior of the wrist is called the
carpal tunnel.
Collapse of this hollow area results in entrapment of the median nerve, a condition known as

Out inate defenses
convey blood away from the heart
arteries
