Mastering ch.3 Tissues

Which of these are visible characteristics of stratified squamous epithelium?

-The squamous cells closer to the lumen are flatter while the squamous cells closer to the connective tissue are fuller and rounder. -There are so many layers of cells that it would be difficult to count them precisely. -Stratified squamous epithelium is always adjacent to a free space or lumen.

Identify the primary functions of simple columnar epithelium.

Absorption Secretion

Which type of connective tissue is unusual in having relatively little extracellular matrix?

Adipose

Where is the basement membrane located?

At the boundary between connective tissue and epithelium

Which tissue is an excitable tissue?

What is the dominant fiber type found in dense irregular connective tissue?

Collagen

What are the fiber types found in the two forms of dense regular connective tissue?

Collagen and elastic

What are the visible characteristics of dense regular connective tissue?

Collagen fibers or elastic fibers running in the same direction. Very little ground substance and few cells are observable on the slide. Fibroblast nuclei are visible, sporadically located between fibers.

Diffusion Filtration

What fiber type permits areolar connective tissue to retain a degree of flexibility?

Elastic

Where is stratified squamous epithelium found in the body?

Epidermis Lining of the vagina Lining of the esophagus

What are the visible characteristics of dense irregular connective tissue?

Fibers create a woven or web-type pattern observable on the slide. Collagen fibers running in different directions. Fibroblast nuclei are visible in a sporadic arrangement.

What are the visible characteristics of areolar connective tissue?

Fibers create an observable woven or web-type pattern. Multiple cell types are present. Multiple types of fibers running in different directions.

What does the term "regular" in "dense regular connective tissue" refer to?

Fibers run parallel.

Where is dense regular connective tissue found in the body?

Forms tendons Forms part of the wall of large arteries

Where would ciliated epithelial be found?

In the trachea

Where are chondrocytes located?

Inside lacunae

Glucose moves from the plasma into a skeletal muscle cell, where it is used for energy. Through which fluid compartment does glucose move between the plasma and the skeletal muscle cell?

Interstitial fluid

Define interstitial fluid, indicating whether it is inside (intracellular) or outside (extracellular) cells.

Interstitial fluid is extracellular fluid outside the circulatory system and the cells.

Where is simple squamous epithelium found in the body?

Kindeys, Lining of blood vessels, Air sacs of the lungs

Where is simple columnar epithelium found in the body?

Lining the uterine (fallopian) tubes Lining the stomach Lining the small and large intestine

What type of connective tissue is areolar connective tissue?

Loose connective tissue

Which is the name of the hollow interior of an organ?

Lumen

What visual feature sets hyaline cartilage apart from other types of cartilage?

Matrix appears transparent.

What is the function of cilia?

Movement of something across the cells surface

Where is hyaline cartilage found in the body?

Nose Joints Trachea

Which two fluid compartments make up the extracellular fluid?

Plasma and interstitial fluid

Part complete What is the function of stratified squamous epithelium?

Protection

Provides strength Provides structural support

Identify the primary function(s) of dense regular connective tissue.

Provides strength and durability Resists bidirectional tensions applied along one spatial plane

Identify the primary function(s) of dense irregular connective tissue.

A single layer of tall rectangular cells best describes which of the following?

Simple columnar epithelium

Which of these are characteristics of simple squamous epithelium?

Simple squamous epithelium is found next to free space called the lumen. Simple squamous cells attach to form a sheet-like arrangement.

Having multiple layers of flat cells against a free surface describes which of the following?

Stratified squamos epithelium

Identify the primary functions of areolar connective tissue.

Supports epithelium Connects different tissue types

Describe the apical surface.

The apical surface is closest to or on the luminal surface. Secretions from goblet cells are released from the apical surface of a cell. The apical surface is sometimes covered with cilia.

Where is areolar connective tissue found in the body?

Underlying the epithelium of the esophagus Underlying the epidermis Underlying the epithelium of the trachea
