Muscle tissue Flashcards
is composed of cells that are specialized to
shorten in length by contraction
Muscle tissue
This contraction result in
movement
CLASSIFICATION OF MUSCLE
- Skeletal Muscle
- Cardiac Muscle
- Smooth Muscle
are called striated muscles because when we observed this under the microscope they have a striped like appearance
Skeletal muscles
is present in the limbs and body wall.
Because of its close relationship to the bony skeleton this variety is called
skeletal muscle.
Location: Myocardium
❖ Nucleus: single nucleus
❖ Capillary plexus: Extremely rich
❖ Nerve supply: ANS
❖ Contraction: involuntary
Cardiac Muscle
also sometimes known as Involuntary
muscle due to our inability to control its movement, or nonstriated as it does not have the stripy appearance of
Skeletal muscle.
Smooth Muscle
found in the walls of hollow organs such as
the Stomach, Esophagus, Bronchi and in the walls of blood
vessels.
Smooth muscle
Structure: Shorter cells
One nucleus per cell
No visible striations
Smooth Muscle
wave like movement pushes food
through digestive system
Peristalsis
Function of Muscle Tissue
Involuntary movement
Peristalsis
Location of Smooth Muscle
Walls of hollow internal organs
Stomach, Intestines, Bladder, Uterus,
Blood vessels
MUSCLE TISSUE TYPES
Skeletal
Smooth
Cardiac
Attached to bones
Nuclei multiple and peripherally located
Striated, Voluntary, and Involuntary
(reflexes)
Skeletal
Walls of hollow organs, blood vessel, eye
glands, skin
Single nucleus centrally located
Not striated, involuntary, gap junctions in
visceral smooth
