Question | Answer |
Cells in muscle tissues are called | called muscle fibers due to their elongated shape |
Muscle tissues are_________meaning they can shorten and thicken | __________tissues are contractile |
three types of muscle tissue | skeletal, smooth, and cardiac are |
Skeletal muscle tissue forms | forms muscles that usually attach to bones and that are controlled by conscious effort |
Skeletal muscle tissue is under | under conscious control and is therefore called voluntary |
Striations of skeletal muscle tissue | alternating light and dark cross-markings |
Skeletal muscle tissue functions | functions to move body parts and in swallowing and breathing |
Smooth muscle tissue is called | called smooth because it lacks striations |
Smooth muscle tissue located | located in walls of most hollow internal organs |
Smooth muscle | involuntary because it cannot be consciously controlled |
Cardiac muscle tissue is located | muscle tissue located only in the heart |
An intercalated disc | a specialized intercellular junction located only in cardiac muscle tissue |
Like skeletal muscle, cardiac muscle is | striated |
Like smooth muscle, cardiac muscle is | involuntary |
Nervous tissues are found | found in the brain, spinal cord, and peripheral nerves |
neurons | The basic cells of nervous tissue |
Epithelial membranes | composed of epithelial and underlying connective tissues |
Three types of epithelial membranes | serous, mucous, and cutaneous |
Serous membranes line | line the body cavities that lack opening to the outside and secrete serous fluid |
Mucous membranes line | line the cavities and tubes that open to the outside of the body |
The cutaneous membrane | called skin |
Neurons, or nerve cells | sensitive to changes in their surroundings and respond to stimulation of impulses along nerve fibers |
neuroglial cells serve | serve to support the neurons and bind the nervous tissue together |
Neuroglial cell | carry on phagocytosis and bring nutrients to the neurons as well as remove waste from cells |
Epithelial membranes | cover body surfaces and line body cavities and organs |
Synovial membranes | line joints |
Serous membranes | line body cavities |
Mucous membranes | line the cavities and tubes that open to the outside of the body |
