Which of the following statements are correct concerning nervous tissue? The cell body is the metabolic center and contains the nucleus and other organelles. Dendrites receive impulse from other neurons. Axons conduct impulses to another neuron or tissue. All of these are correct

All of these are correct

Which of the following statements is/are correct? Mucous membranes would be found lining the digestive tract, respiratory tract and reproductive tract. Serous membranes such as the pleura line the thoracic cavity and cover the lungs. The skin is a cutaneous membrane. All of these are correct.

All of these are correct.

Which of the following characteristics are shared by all epithelial cells? Cells are arranged in continuous sheets. There is little space between plasma membranes. All cells have a free surface. All of these characteristics are shared by all epithelial cells.

All of these characteristics are shared by all epithelial cells.

The basic types of human tissues are: Epithelial, Connective, Muscular and Nervous Epithelial, Membranous, Muscular and Nervous Muscular, Nervous, Epithelial and Mesenteric Epithelial, Connective, Muscular and Glandular

Epithelial, Connective, Muscular and Nervous

Epithelial and connective tissues are found adjacent to each other because: Epithelium is avascular and needs to exchange oxygen, nutrients and waste with the blood of highly vascular connective tissue. Connective tissue is avascular and needs to exchange oxygen, nutrients and waste with the blood of the highly vascular epithelium. The two tissues are seldom adjacent to each other. The two are coupled by gap junctions to allow for nutrient, oxygen and waste exchange.

Epithelium is avascular and needs to exchange oxygen, nutrients and waste with the blood of highly vascular connective tissue.

Which of the following statements is incorrect? Endocrine glands secrete products directly into the blood stream while exocrine glands secrete their products to a surface through ducts. Merocrine glands release products from the cell in secretory vesicles by exocytosis. Apocrine glands release products by pinching off the part of the cell containing them Holocrine glands release products by rupturing the cell Exocrine glands secrete products directly into the blood stream while endocrine glands secrete their products to a surface through ducts.

Exocrine glands secrete products directly into the blood stream while endocrine glands secrete their products to a surface through ducts.

Each serous membrane is divided into a parietal layer and a visceral layer. The visceral layer is attached to and lines the wall of the body cavity. True False

False

Which of the following is mismatched? Adipocytes - Store large drops of triglycerides. Dense regular connective tissue - Contains parallel bundles of connective tissue that resist stretching in structure like tendons. Reticular tissue - Contains reticular fibers which make up the framework of organs like the liver. Elastic connective tissue - Is found in large arteries and allows stretching. Fibrocartilage - Contains stacks of chondrocytes and is designed to withstand pressure in structures such mucous membranes.

Fibrocartilage - Contains stacks of chondrocytes and is designed to withstand pressure in structures such mucous membranes.

These cell junctions provide electrical and chemical communications between cells. Tight junctions Adherens junctions Desmosomes Hemidesmosomes Gap junctions

Gap junctions

Which of the following statement is incorrect? Simple squamous epithelium is found in thin layers so substances can pass through them rapidly. Transitional epithelium change shape to allow structures such as the urinary bladder to distend and collapse. Keratinized stratified squamous epithelium is adapted for absorption. Ciliated simple columnar epithelium moves mucus by ciliary action.

Keratinized stratified squamous epithelium is adapted for absorption.

Tissue regeneration is possible if _______ (cells) accomplish the repair. Fibroblasts Parenchymal Neuroglial Amitotic

Parenchymal

Which of the following statements is incorrect? Simple squamous epithelium consists of one layer of long thin rectangular cells. Stratified cuboidal epithelium consists of two or more layers of cube shaped cells. Pseudostratified epithelium has nuclei at different heights but all cells rest on the basement membrane. Transitional epithelium is a type of stratified epithelium.

Simple squamous epithelium consists of one layer of long thin rectangular cells.
