Memmler Chapter 4 (Tissues, Glands, and Membranes) Flashcards
Tissues
Groups of cells similar in structure, arranged in a characteristic pattern.
Epithelial Tissue
Covers surfaces, lines cavities, and forms glands
Connective Tissue
Supports and forms the framework of all parts of the body
Muscle Tissue
Contracts and produces movement
Nervous Tissue
Conducts nerve impulses
Squamous (Epithelial)
Flat and irregular
Cuboidal (Epithelial)
Square
Columnar (Epithelial)
Long and Narrow
Exocrine Glands
Produce secretions that are carried out of the body.
Endocrine Glands
Secrete not through ducts but directly into surrounding tissue fluid
Circulating Connective Tissue
Has a fluid consistency; its cells are suspended in a liquid matrix.
Loose Connective Tissue
Has a soft consistency, similar to jelly
Dense Connective Tissue
Contains many fibers and is quite strong, similar to a rope or canvas fabric
Cartilage
Has a very firm consistency.
Bone Tissue
The hardest type of connective tissue
Muscle Tissue
Capable of producing movement by contraction of its cells, which are called muscle fibers because most of the mare long and threadlike.
Skeletal Muscle
work with tendons and bones to move the body
Cardiac Muscle
Forms the bulk of the heart wall know as the myocardium. Produces the regular contractions known as heartbeats
Smooth Muscle
involuntary muscle it forms the walls of the hollow organs in the ventral body cavities including the stomach, intestines, gallbladder, and urinary bladder.
Neuron
The basic unit of nervous tissue
Neurogila
Nervous tissue supported and protected with tehse specialized cells. Protect the brain from harmful substances
Membranes
Thin sheets of tissue
Epithelial Membrane
its outer surface is made of epithelium. Undertheath there is a layer of areolar/dense connective tissue that strengthens the membrane.
Serous Membranes (Epithelial)
line the walls of body cavities and are folded back onto the surface of internal organs, forming their outermost layer
Mucous Membranes (Epithelial)
Line tubes and other spaces that open to the outside of the body
Cutaneous Membrane (Epithelial)
Commonly known as the skin, has an outer layer of stratified squamous epithelium
Serous Membranes
Line the closed ventral body cavities and do not connect with the outside of the body
Pleurae
Line the thoracic cavity and cover each lung
Serous pericardium
forms part of a sac that encloses the heart, which is located in the chest between the lungs
Peritoneum
The largest serous membrane. It lines the walls of the abdominal cavity, covers the abdominal organs ,and forms supporting and protective structures.
Mucous Membranes
Are so named because they contain goblet cells that produce mucus. These membranes form extensive continuous linings in the digestive, respiratory, uriniary, and reproductive systems.
Synovial Membranes
Thin layers of areolar tissue that line the joint cavities. They secret a lubricating fluid that reduces friction between the ends of the bones.
Fascia
Refers to fibrous bands of sheets that support organs and hold them in place.
