Epithelium, Muscle, Connective, Nervous
What are the four general categories of tissue?
single layer of cells
simple
Name 3 shapes of epithelial cells
squamous, cuboidal, columnar
3 categories of muscle tissue
skeletal, smooth (visceral), cardiac
Name 2 types of supportive connective tissue
osseous (bone) and cartilage
Covers, lines, and forms glands
Epithelium
multiple layers of cells
stratified
The walls of the alveoli of the lung and why
simple squamous, thin to allow efficient oxygen/carbon dioxide exchange between environment and blood.
striated
skeletal, cardiac
Name three types of cartilage
Hyaline, Elastic, Fibrocartilage
Contracts
Muscle
all cells rest on basement membrane but all do not reach the free surface
pseudostratified
the lining of the esophagus and why
stratified squamous, layers provide protection as food passes through
multinucleated
skeletal
Cartilage cells are called _____.
Bones cells are called_____.
Both are found in spaces called_____.
chondrocytes, osteocytes
both located in spaces called lacunae
Support, transport, energy reserves
Connective
General rule for naming stratified epithelium
cell shape at free surface determines name
Kidney tubules feature ___ epithelium which is specialized for _____.
simple cuboidal, specialized for secretion/absorption
bifurcated, intercalated discs
cardiac
Intervertebral discs feature what type of cartilage and why?
Fibrocartilage, strongest type, provides support between vertebrae of spine
communication by way of electrochemical impulses
Nervous (Neural)
Name, explain why this epithelium does not follow the general rule for naming and state a location in the body
Transitional, surface cells change shape as bladder expands and recoils
Explain the difference in function between cilia and microvilli. State a location of epithelium featuring each.
Pseudostratified ciliated columnar epithelium lines the trachea. Cilia sweep mucus away from lungs.
Simple columnar epithelium lines small intestine. Microvilli are specialized for absorption
Compare muscle types in terms of control, striations, number of nuclei, and location
skeletal- voluntary, striated, multinucleated, attached to bones
smooth- involuntary, nonstriated, uninucleated, intestinal tract
cardiac- involuntary, striated, uninucleated, heart
Which supportive connective type is more capable of repair? How is degree of vascularity related?
Osseous (bone) is more vascular and more capable of repair since blood brings oxygen and nutrients.
Cartilage is avascular and must get nutrients by diffusion. It heals slowly if at all.
