Muscular Tissues Flashcards
Is specialized for contraction
having properties of
extensibility, elasticity and
contractility. It is highly
vascularized and innervated.
Muscular tissues
Packaged by connective tissue sheets into skeletal muscles,
which are attached to the skeleton and pull on bones or
skin
Skeletal muscle tissue
Characteristics of skeletal muscle cells
Striations (stripes)
Multinucleate (more than one nucleus)
Long, cylindrical shape
description of muscle tissues
Voluntarily (consciously) controlled
Produces gross body movements or facial expressions
3 types of muscle tissues and cells
Smooth muscles
Cardiac muscles
Skeletal muscles
appear striated, cell are large, long and cylindrical, with nuclei
Skeletal muscle
Movement of the body, under voluntary control
Skeletal muscle
Attached to bone or other connective tissues
Skeletal muscle
cells are cylindrical and striated and have a single nucleus, they are branched and connective to one another by intercalated disks, which contain gap junction.
Cardiac muscle
Pumps the blood; under involuntary control
cardiac muscle
found in the heart
cardiac muscle
cells are tapered at each end, are not striated, and have a single nucleus
Smooth muscle
Regulates the size or organs, forces fluids through tubes, controls the amount of light entering the eye, and produces “goose bumps” in the skin
Smooth muscle
under involuntary control
Smooth muscle
Found in hollow organs, such as the stomach and intestine, skin and eyes
