Muscular Tissue Flashcards
- The nucleus of skeletal muscle is found:
- This arrangement is known as?
- along the edges of the cell
- Peripheral nuclei
Groups of muscle cells/fibers known as:
Fasicle
Insertion (I)
More moveable point of muscle attachment
3 types of muscle cells:
1) Smooth 2)Cardiac 3)Skeletal
Muscle of movement:
Skeletal muscle
Origin (O)
less moveable point of muscle attachment
What is the pupose of peripheral nuclei in skeletal muscle cells?
Provides ample room inside the cells for fibers that cause contraction
what controls skeletal muscle?
Somatic division of nervous system
what does skeletal muscle attach to?
Skin, skeleton, or other muscles
Muscular tissue
cells that have the ability to contract
2 kinds of ways muscles are anchored onto the body:
- Tendon
- Aoneurosis
Cells that have many nuclei are known as:
Multinuceate cells
Muscle cells that are found in the heart walls
cardiac muscle
Prime mover:
Main muscle that does most of the action
Connective tissue that surrounds each muscle cell:
Endomusium
Synergist muscles
muscles that aid the prime mover
Aponeurosis
Sheet-like attachment
Connective tissue that surrounds fasicles
Perimysium
what controls smooth muscle?
Autonomic Nervous System
Tendon
Chord-like attachment
Antagonist muscle
Muscles whose actions are opposite of the prime mover
Many fasicles are wrapped together by:
Epimysium
Muscle cells that make up the walls of hollow organs
Smooth muscle
examples of organs that contain smooth muscle
Bladder, esophagus, stomach, blood vessels
Function of skeletal muscle
Pull body parts closer to one another
Appearance of skeletal muscle cells
- Vary in length (up to 36 inches)
- Cylinder-shaped
- Have many nuclei
what controls cardiac muscle?
Autonomic Nervous System
Action of muscle
As muscle contracts, the insertions point is brought closer to the origin
Also known as: flex, extend, etc…
