A tissue that has the ability to contract, or shorten, making movement possible
Muscular Tissues
Muscular Tissues are composed of numerous fine fibrils called:
Myofibrils
Two kinds of muscles in the body:
Voluntary Muscle and Involuntary Muscle
Voluntary Muscles are also called?
Striated / Skeletal
Muscle Tissues that are closely attached to skeletal bones
Skeletal/Striated Muscle
Striated is also called?
Striped
They are muscle tissues bundled together in a parallel
Skeletal / Striated Muscle
Smooth Muscle is also called?
Non-Striated / Visceral
A type of muscle tissue found in thewalls of hollow organs
Smooth / Visceral Muscle
Visceral is found in:
the intestines, uterus and stomach
Fusi-form means?
Taper at both ends
taper at both ends and do not show striations
Smooth / Visceral Muscle
Cell junctions hold them together and they are bundled together in a connective tissue sheath
Smooth / Visceral Muscle
A contractile tissue present only in the heart
Cardiac Muscle Tissue
Cylindrical in shape, they have branches and there is a single nucleus
Cardiac Muscle Tissue
Performs rhythmic contraction and relaxation throughout life
Cardiac Muscle Tissue
Consists of individual heart muscle cells connected by intercalated discs to work as a single functional organ
Cardiac Muscle Tissue
Cardiac Muscle Tissue is the:
- Contractile Tissue
- Rhythmic contraction and relaxation
- Cylindrical, branched and has single nucleus
- individual muscle cells connected by intercalated discs to work as single organ
Visceral Muscle is the:
- found in the walls of hollow organs
- fusi-form and no striations
- held by cell junctions in a connective tissue sheath
- involuntary
Skeletal Muscle is the:
- attached to the bone
- striped and bundled together in parallel
