Epithelial, Connective, Muscle and Nervous Tissue Analysis Questions

What is the difference between areolar, adipose, and reticular tissue?

Areolar Connective Tissue--- Location: Around blood vessels, nerves, and organs. Function: Provides strength, elasticity, support and immune system protection. Adipose Connective Tissue (Fat)--- Function: Store energy, provide protection, and insulate. Location: Around organs, subcutaneous layer(between skin and muscle) Reticular Connective Tissue--- Location: Around organs such as the liver, kidney, spleen, and lymph organs. Function: To support and hold together organs and adipose tissue (fat).

What is the difference between hyaline, elastic, and fibrocartilage?

Hyaline cartilage - consists of rounded collagen which makes it hard and like marble. It is usually found in movable joints. Elastic cartilage - made of elastic fibers and collagen in a wavy pattern that makes it flexible like rubber. It is found in your ears and nose. Fibrocartilage - contains both type I and type II arranged in bundles. This makes it strong and slightly flexible and well suited for its main job as intervertebral discs in your spine

What is the difference between regular and irregular dense tissue?

Irregular D.T can resist tension in multiple directions and has no definite arrangement of collagen fibers. Regular D.T is parallel to each collagen fiber and can resist tension greatly in a single direction.

How is the shape of a neuron suited to its purpose?

Neurons are really long and thin so they can cover large areas of the body to send electrical signals more efficiently.

What is the difference between neurons and neuroglia?

Neurons are responsible for sending and receiving messages while neuroglia provide support and nutrients for neurons.

What type(s) of epithelial tissue can be found in the lungs?

Simple Squamous in lung sacs Stratified columnar in lungs

What type(s) of epithelial tissue can be found in the stomach?

Simple columnar

What is the difference between skeletal, smooth, and cardiac muscle?

Skeletal muscles - attached to your skeleton and tendons and are able to move at will or voluntary. Smooth muscle - "involuntary muscle" that makes up the lining of most of the organs of the body. Cardiac muscle - the heart, is an extremely dense strong tissue. large number of mitochondria.

What type(s) of epithelial tissue can be found in the sweat glands?

Stratified Cuboidal

What is the difference between stratified squamous, stratified cuboidal, and stratified columnar epithelial tissues?

Stratified squamous -2 or more layers of small thinner cells stratified cuboidal cells - multiple layers of cube shaped cells stratified columnar cells - multiple layers of column shaped cells.

What type(s) of epithelial tissue can be found on the surface of the skin?

Stratified squamous cells

What is the difference between compact and spongy bone?

The compact bone has a continuous matrix with no gaps while the spongy bone has numerous branching bony plates. The irregular connecting spaces between the plates help reduce the bone's weight in the spongy bone.

What is an intercalated disc? Why are these not seen in skeletal muscles?

The intercalated disc function is to join cardiac muscle fibers together to continuously pump the heart, not the skeletal muscle.

What is the difference between loose and dense connective tissue?

The loose connective tissue - found beneath the epithelial tissue that lines the internal body surfaces, glands, and around small vessels. Dense connective tissue - found on the outside of many organs, in the dermis of the skin and submucosa, within various organs as dense irregular connective, and in tendons, ligaments, and aponeuroses as dense regular connective tissue.

What are the lines in skeletal and cardiac muscle?

Those are striations in the muscle

What type(s) of epithelial tissue can be found in the bladder?

Transitional Epithelium

What is the difference between transitional and pseudo-stratified epithelial tissues?

Transitional is multiple layers of different types of cells. Pseudostratified is a single layer of different sized cells.

What is the difference between simple squamous, simple cuboidal, and simple columnar epithelial tissues?

simple Squamous cells - small thinner cells that are a single layer thick simple Cuboidal cells - a layer of cube shaped cells simple columnar cells - a layer of column or long cells
