Chapter 4 Flashcards
It is a group of cells with similar structures and functions.
TISSUES
The study of tissues.
Histology
It is a type of gland that has ducts.
Exocrine glands
It is a type of gland which do not have ducts.
Endocrine gland
A tissue that’s one layer thick but appears to be multilayered and is composed of cells taller than they are wide is ______.
Pseudostratified columnar epithelium
These are composed of soft areolar connective tissue and contain no epithelial cells at all.
Synovial Membranes
What is the main cellular mechanism for taking up specific target molecules?
- Receptor- mediated endocytosis
Meaning of (cams)?
Cell adhesion molecules
This layer is known as the layer that is deeper than the Dermis layer of the skin.
Hypodermis
It can be smooth or lined with microvilli or cilia and its smooth type can reduce friction as the material moves across it.
Free Surface
It binds adjacent cells together and forms permeability barriers and prevents the passage of materials between epithelial cells because they surround each cell, similar to the way a belt surrounds the waist.
Tight Junctions
It is a small channel that allows small molecules and ions to pass from one epithelial cell to an adjacent one.
Gap Junctions
It is a secretory organ.
Gland
It involves the release of secretory products by exocytosis
Merocrine secretion
A rope-like structure that connects to the bone and muscles is tendon _____________ connects bone to bone through joints.
Ligaments
Greater amounts of the pigment_______
Melanin
It is the very specialized tissue making up the nervous system.
Nervous Tissue
If the study of the body structure is known as anatomy. How do you refer to the study of tissues?
Histology
True or False. Smooth Muscle is responsible for pumping blood.
False (Cardiac Muscle)
True or False. Reticular fibers are fine collagen fibers that form a branching network that supports other cells and tissues.
TRUE
True or False. In the span of 16 weeks, embryonic tissue becomes specialized to form the types of connective tissues seen in adults.
False (8 weeks)
True or False. Serous membranes contain glands, and they secrete a fluid called serous fluid.
False (serous membrane: no glands)
Endothelium is a specialized type of extracellular material secreted by epithelial and connective tissue cells.
False (Basement membrane)
Is TISSUE MEMBRANE a thin sheet or layer of tissue that covers a structure or lines a cavity? True or False?
True
True or False. Endocrine glands secretes through ducts onto the surface of the gland
False (exocrine glands)
True or False. Cartilage is composed of chondrocytes. It is subdivided into 3 types of cartilage, Hyaline, Fibrocartilage and Elastic Cartilage
True
True or False. Cardiac muscle is known to be the muscle of the heart.
True
True or False. The neuron also known as nerve tissue is responsible for carrying information throughout the human body.
False (nerve cell)
True or False. A thin sheet or layer of tissue that covers a structure is called collagen.
False (tissue membrane)
True or False. Areolar Connective Tissue fills the spaces between organs and holds them in place, also known as the “packing material” of the body.
True
What is epithelium?
A type of body tissue that forms the covering on all internal and external surfaces of your body.
What is a gland ? give its major two types .
Glands are composed of epithelium that is supported by network of connective tissue .The two major types of glands are endocrine and exocrine gland.
What are the functions of connective tissue?
Connective tissues enclose and separate organs and tissues; connect tissues to one another; help support and move body parts; store compounds; cushion and insulate body; transport and substances; and protect against toxins
and injury.
Define Tissue Repair.
Tissue repair is a natural process in which the primary goal is to restore the structure and function of the tissue following an injury.
Describe the classification of connective tissue.
Connective tissue is a diverse primary tissue type that makes up part of every organ in the body.
List the major functions of epithelia.
Protecting underlying structures
Acting as a barrier
Permitting the passage of substances
Secreting substances
Absorbing substances
List the primary tissues of the body.
Epithelial Tissue
Connective Tissue
Muscle Tissue
Nervous Tissue
What are the three layer of tissue make up the skin?
Dermis
Hypodermis
Epidermis
What pigments determine skin color?
Melanin
Carotene
Hemoglobin
Give at least 2 functions of epithelial tissue.
Epithelial tissue perform variety of functions such as;
- Protection
- Secretion
- Absorption
- Excretion
- Filtration
- Diffusion
- Sensory reception
What are the four varieties of membranes?
Serous membranes
Synovial membranes
Mucous membranes
Cutaneous membranes
Name the three types of muscle tissue.
Cardiac muscle
Smooth muscle
Skeletal muscle
Enumerate the correct sequence involved in wound healing.
- Hemostasis Phase.
*Inflammatory Phase.
*Proliferative Phase.
*Maturation Phase (Remodeling Stage)
Classification of Epithelia according to the shape of cells.
Squamous
Columnar
Cuboidal
Classification of Epithelia according to numbers of cell layers.
Simple
Stratified
Pseudostratified
Transitional
