Unit 1: Lab pracitical types of tissues
Simple columnar epithelium
LOCATIONS: gallbladder FUNCTIONS: Protection,secretion, absorption
Simple cuboidal epithelium
LOCATIONS: thyroid gland FUNCTIONS: Limited protection, secretion, absorption
Skeletal muscle tissue
Location: All over the body Function: Movement Structure: Striated, multiple nuclei
simple squamous epithelium
Location: Alveoli of lungs & blood vessels Function:Absorption and diffusion Structure: single layer of flat cell
Adipose tissue
Location: Hypodermis function: Tissue that stores fat.
Dense irregular connective tissue
Location: dermis of skin function: takes tension well. Ability to regain orginal shape after stretching.
Dense regular connective tissue
Location: tendons and ligaments function: good resistance to force
What is the key "identifying feature" of pseudostratified epithelial cells?
May look multi-layered, is a single layer of cells. Each cell is connected to the basement membrane
Name tissue type that is designed to contract? How many forms of this tissue type exist? Name both.
Muscle tissue 3 types - skeletal cardiac smooth
Name tissue type that receives and conducts impulses or signals and is found in the brain and spinal cord (among other places)?
Nervous tissue
Does cartilage a type of connective tissue have abundant blood supply?
No
Epithelial tissue may also be classified as "simple" or "stratified". What do these two terms mean? Explain
One layer - simple Stratified - 2 or more layers
List the function of "Axon"
are responsible for transmitting impulses over long distances from cell body.
Explain your answer based on what you have learned about the connective tissue from the lecture:
because cartilage is an elastic fiber, and fibers don't contain blood.
Bone ( Hard connective tissue)
function: provides protection to internal organs + supports the body
The matrix in the cartilage tissue consists of these two fibers. Name the two types of fibers:
hyaline cartilage, Elastic cartilage
Cartilage ( Hyaline cartilage) - Connective Tissue Type
location: Ends of long bones function: Supports body + allows felixability to diff parts of the body
NERVOUS TISSUE:
location: brain, spinal cord, nerves function: sends nerve singles
Blood ( liquid connective tissue)
location: circulates in the cardivoscular system function: Transports oxygen + Nutrients to lungs +tissue
Areolar connective tissue ( loose connective tissue)
location: upper layer of the dermis
Stratified squamous epithelium
location: vagina function: proctects loss of moisuture + water loss
List the function "Dendrites" in a Neuron cell/ Nervous tissue
receive incoming signals towards the cell body.
Name the tissue type that has "extracellular matrix" made up of ground substance and fibers?
Connective tissue
Why is the nucleus pushed to sides in "adipose tissue cell"?
Because of fat, vacuole takes up much of the space
Name the 4 Types of major tissue in human bodies.
Epithelial Connective Muscle nervous.
What is the key difference between skeletal and smooth muscle?
Skeleton muscle is striated in appearance
Epithelial tissue can be classified according to its cell shape. Name all 3 shapes?
Squamous cuboidal columna
Does bone tissue have abundant blood supply?
yes
