Epithelium and Glands (PPT based) Flashcards
four basic types of tissues:
Nervous
Epithelial
Muscle
Connective
What type of tissue:
Elongated cells with extremely fine processes
Nervous
What type of tissue:
Aggregated polyhedral cells
Epithelial
What type of tissue:
Elongated contractile cells
Muscle
What type of tissue:
Several types of fixed and wandering cells
Connective
The ECM of what type of tissue:
Very small amount
Nervous
The ECM of what type of tissue:
Small amount
Epithelial
The ECM of what type of tissue:
Moderate amount
Muscle
The ECM of what type of tissue:
Abundant amount
Connective
MAIN FUNCTIONS of what type of tissue:
Transmission of nerve impulses
Nervous
MAIN FUNCTIONS of what type of tissue:
Lining of surface or body cavities, glandular secretion
Epithelial
MAIN FUNCTIONS of what type of tissue:
Strong contraction; body movements
Muscle
MAIN FUNCTIONS of what type of tissue:
Support and protection of tissues/organs
Connective
The two forms of epithelium and glands:
Sheets of contiguous cells that _____ the body on its external surface and line the body on its internal surface
cover
The two forms of epithelium and glands:
As _______, which originate from invaginated epithelial cells
glands
oral and nasal mucosae, cornea, epidermis of the skin and the mammary glands
Ectoderm
liver, pancreas, and the lining of the respiratory and gastrointestinal tract
Endoderm
uriniferous tubules of the kidney, lining of the male and female reproductive systems, endothelial lining of the circulatory system, and the mesothelium of the body cavities
Mesoderm
FUNCTIONS OF EPITHELIUM AND GLANDS:
Protection
Transcellular Transport
Secretion
Absorption
Selective permeability
Detection of sensations
Avascular, tightly bound contiguous cells forming sheets covering or lining the body
