Which of the following DOES not describe the function of the Muscular Muscle?

• Movement of the body

• Maintenance of Posture

• Constriction of the Muscles

• Production of Heat and Cold

Give the order of structure of muscles from the whole muscle down to the smallest unit.

• Fascicle – Muscle Fiber - Myofilaments

• Fascicle – Myofiber – Actin Myofilaments

• Fascicle – Single Muscle Fiber – Myosin Myofiber

• Fascicle – Myofibrils – Myofiber

A connective tissue covering the muscle fibers

• Exomysium

• Perimysium

• Endomysium

• Epimysium

The two kinds of protein fibers are:

• Myosin Myosfilament and Actin Myosfilament

• Myosin fiber and Actin Myosinfilament

• Actin Myofilament and Myosin Myofilament

• A and C is true

This is the cell membrane of the Muscle Fiber.

• Sacrolema

• Sacromelemma

• Sarcolemma

• Sacroreticulum

It stores calcium which can then be released into the sarcoplasm when an action potential is conducted along the sarcolemma of the T-tubule.

• Sarcoplasmic Smooth Reticulum

• Sarcoplasmic Rough Reticulum

• Sarcoplasmic Cisternae

• Sarcoplasmic Reticulum

Consists of fine protein filaments that anchor the myosin myofilaments in place.

•     M Line

•   I Line

• Z Line

• H Line

These are specialized nerved cells that stimulate muscles to contract.

• Motor Unit

• Motor Neuron

• PostNeuron

• Nucleus

Consisting of two pairs, are deep to the mandible

The muscle that flexes the head and neck
