  2. This arrangement is known as?
A
  1. along the edges of the cell
  2. Peripheral nuclei
2
Q

Groups of muscle cells/fibers known as:

A

Fasicle

3
Q

Insertion (I)

A

More moveable point of muscle attachment

4
Q

3 types of muscle cells:

A

1) Smooth 2)Cardiac 3)Skeletal

5
Q

Muscle of movement:

A

Skeletal muscle

6
Q

Origin (O)

A

less moveable point of muscle attachment

7
Q

What is the pupose of peripheral nuclei in skeletal muscle cells?

A

Provides ample room inside the cells for fibers that cause contraction

8
Q

what controls skeletal muscle?

A

Somatic division of nervous system

9
Q

what does skeletal muscle attach to?

A

Skin, skeleton, or other muscles

10
Q

Muscular tissue

A

cells that have the ability to contract

11
Q

2 kinds of ways muscles are anchored onto the body:

A
  1. Tendon
  2. Aoneurosis
12
Q

Cells that have many nuclei are known as:

A

Multinuceate cells

13
Q

Muscle cells that are found in the heart walls

A

cardiac muscle

14
Q

Prime mover:

A

Main muscle that does most of the action

15
Q

Connective tissue that surrounds each muscle cell:

A

Endomusium

16
Q

Synergist muscles

A

muscles that aid the prime mover

17
Q

Aponeurosis

A

Sheet-like attachment

18
Q

Connective tissue that surrounds fasicles

A

Perimysium

19
Q

what controls smooth muscle?

A

Autonomic Nervous System

20
Q

Tendon

A

Chord-like attachment

21
Q

Antagonist muscle

A

Muscles whose actions are opposite of the prime mover

22
Q

Many fasicles are wrapped together by:

A

Epimysium

23
Q

Muscle cells that make up the walls of hollow organs

A

Smooth muscle

24
Q

examples of organs that contain smooth muscle

A

Bladder, esophagus, stomach, blood vessels

25
Q

Function of skeletal muscle

A

Pull body parts closer to one another

26
Q

Appearance of skeletal muscle cells

A
  • Vary in length (up to 36 inches)
  • Cylinder-shaped
  • Have many nuclei
27
Q

what controls cardiac muscle?

A

Autonomic Nervous System

28
Q

Action of muscle

A

As muscle contracts, the insertions point is brought closer to the origin

Also known as: flex, extend, etc…
