Chapter 4 Tissues
- The four primary tissue types are
- epithelial, cartilage, muscle, and brain.
- connective, eipithelial, skin, and blood.
- epithelial, connective, muscle, and nerve.
- glands, bone, lungs, and kidney.
- bone, skin, blood, and muscle.
- Epithelial tissue is characterized by
- tightly packed cells.
- absence of any basement membrane.
- extensive extracellular matrix.
- a rich blood supply.
- both tightly packed cells and a rich blood supply.
- Which of the following characteristics is NOT consistent with simple squamous epithelial tissue?
- little extracellular material
- rest on a basement membrane
- has good blood supply within it
- the cells are thin and flat (not thick)
- acts as a permeability barrier
- What is a small protein channel that allows the passage of ions and small molecules between cells?
- hemidesmosomes
- zonula adherens
- zonula occludens
- gap junction
- Desmosomes
- What type of epithelial tissue is found in the kidney tubules?
- simple cuboidal epithelium
- simple columnar epithelium
- stratified squamous epithelium
- pseudostratified ciliated columnar epithelium
- transitional epithelium
- The secretions of endocrine glands are released directly
- onto the skin surface.
- into the bloodstream.
- into a gland duct.
- into the nervous tissue.
- into the lumen of a tube.
- A general characteristic of connective tissue is that it
- consists of cells with much extracellular material (matrix) between them.
- has no blood supply to the tissue.
- covers the outside of organs.
- is commonly found lining body cavities.
- Cartilage heals slowly after an injury because
- this tissue type is very complex.
- it contains so much proteoglycan.
- it has few, if any, blood vessels.
- it is a dead, rather than a living, tissue.
- it contains no fibroblasts.
- What type of muscle is found in the wall of the digestive tract?
- skeletal muscle
- smooth muscle
- cardiac muscle
- Which of the following is correctly matched?
- neurons – supportive cells of the nervous system
- axons – conduct action potentials away from the cell body
- neuroglia – the conducting cell of the nervous system
- dendrite – rapidly dividing cell
- axon – carry action potentials toward the cell body
Chapter 5 Integumentary System
- The integumentary system has many functions, one of which is
- protection from cancer.
- production of Vitamin E.
- detection of painful stimuli.
- regulation of acid-base balance.
- prevention of albinism.
- Keratinocytes
- produce skin pigments in cell organelles called melanosomes.
- are found in both the dermal and the epidermal layers of the skin.
- are special cells of the immune system.
- are responsible for the reduction of water loss from the skin.
- determine thickness of the skin.
- The stratum basale
- is easily shed when you rub your hands together.
- has a mixture of living and dead cells – mostly dead.
- contains many blood vessels that nourish the epidermis.
- contains cells that undergo mitosis to form new epidermal cells.
- contains cells that undergo meiosis to form new epidermal cells.
- Melanin
- is transferred to other cells by osmosis.
- is increased with exposure to infrared light.
- is absent in individuals known as albinos.
- is a pigment produced by cells in the stratum corneum.
- makes the skin lighter.
- Fingerprints and footprints are produced by projections into the epidermis called
- cleavage lines.
- reticular lines.
- Which of the following statements concerning the hypodermis is false?
- Hypodermis is referred to as subcutaneous tissue.
- Hypodermis is composed of dense connective tissue with collagen and elastin fibers.
- The main cell types of the hypodermis are fibroblasts, fat cells, and macrophages.
- The hypodermis attaches the skin to underlying bone and muscle.
- The hypodermis is a site of fat storage.
- The portion of a hair that protrudes above the surface of the skin is the
- hair bulb.
- hair root.
- hair shaft.
- hair follicle.
- dermal papilla.
- Sweat
- is a hypertonic fluid.
- is produced by a merocrine or apocrine gland.
- contains only water.
- reaches the body only through the hair follicles.
- is not associated with emotions.
- The nail root and the nail body attach to the
- nail bed.
- nail groove.
- An abrasion of the skin results in which of the following?
- fluid retention by the kidney
- increased melanin production
- portal of entry for microorganisms
- loss of cell regeneration ability
- irreversible damage to the epidermis
