Connect ch.5 tissue

Epithelial Tissue

1. Always avascular; cells receive nutrients from deeper tissue layers. 2. Lines surfaces and cavities. 3. Comprised granular tissue.

Connective Tissue

1. Contains high levels of extracellular matrix. 2. Most abundant form of tissue 3. Serves as a transitional tissue between two different tissue types.

Nervous Tissue

1. Functions to provide fast forms of communication.

Muscular Tissue

1. Provides movement of the body segments as well as movement through the body. 2. Heavily vascularized, which denotes high rates of energy consumption.

Which of the following is/are components of a membrane? Check all that apply.

Epithelium Lamina propria (Aerolar Connective Tissue) Connective Tissue Bone Neurons

Which of the following is/are functions of connective tissue? Check all that apply.

Supporting the internal frame of the body Energy storage Hormone transport Protecting the vital organs Forming the structural framework of the liver

Epithelium that consists of more than one layer of cells is called __________.

stratified

Consider the two different ways that tissues can change. Differentiation & Metaplasia

Differentiation 1. Cells in the ectoderm develop into the stratified squamous epithelium of the epidermis. 2. Mesenchyme gives rise to bone tissue. 3. Stem cells turn into specific mature cells. Metaplasia 1. Mature tissue turns into another type of mature tissue. 2. A bladder stone causes transitional epithelium to turn into squamous cells. 3. Acid reflex causes esophageal squamous cells to turn into columnar cells.

Consider the three different types of cell growth.

Hyperplasia 1. Cells grow in number. 2.Most childhood tissue grows this way. 3. Achieved via cell division. Hypertrophy 1. Cells grow in size. 2. Muscle tissue grows this way. 3. Adipose tissue grows this way. Neoplasia 1. Abnormal, nonfunctioning tissue. 2. Tumor cells.

Decide the outcome of the hypothetical situation by dragging the label into the appropriate category.

Increase 1. Tissue damage would increase if the epidermis of the skin was composed of nonkeratinized tissue. 2. Flexibility of the intevertebral discs increase of the fibrocartilage was replaced with elastic cartilage. 3. Rate of infection increases if the epidermis was composed of pseudo stratified epithelium tissue. 4. The vascularity of ligaments increase if they were made of bone. Decrease 1. Diffusion rates of oxygen would decrease if the alveolar lining of the lungs were made up of stratified epithelium. 2. Involuntary control of involuntary digestive mobility would decrease if the intestines contained skeletal muscle. 3. Elasticity of the ear would decrease if the elastic cartilage was replaced with bone. 4. Protection of the brain would decrease if the skull was made up of hyaline cartilage.

Which of the following are cells found in connective tissue? Check all that apply.

Leukocyte Muscle fiber Red blood cell Neuron Chondrocyte

which type of epithelia it pertains.

Simple 1. Every cell touches the basement membrane. 2. Allows for rapid diffusion of substances 3. Lines the lumen of the renal tubules of the kidney. Stratified 1. Some cells rest on other cells. 2. Resists abrasions 3. Found on the superficial surface of the skin. 4.found in sweat gland ducts. 5. Is sometimes Keratinized.
