Terms in this set (5)

  • Excitability- can be stimulated by chemical signals, nerves and stretch.
  • Conductivity- the signal for a muscle to contract is spread from the point of stimulation throughout the entire muscle.
  • Contractility- ability of the muscle to shorten.
  • Extensibility-
  • Elasticity-

What are the 4 main characteristics of muscle tissue?

All muscle tissues have 4 characteristics in common:

  • excitability.
  • contractility.
  • extensibility – they can be stretched.
  • elasticity – they return to normal length after stretching.

What are 10 interesting facts about muscles?

Fun Facts About the Muscular System You Didn’t Know

  • Muscles are divided into three types: smooth, cardiac, and skeletal.
  • Your body contains more than 600 muscles.
  • Muscles are made up of special cells called muscle fibers.
  • The largest muscle in the body is the gluteus maximus.

What are the 4 functions of muscles?

The five main functions of the muscular system are movement, support, protection, heat generation and blood circulation:

  • Movement. Skeletal muscles pull on the bones causing movements at the joints.
  • Support. Muscles of the body wall support the internal organs.
  • Protection.
  • Heat generation.
  • Blood circulation.

Where is muscle tissue found?

Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control. Skeletal muscle fibers occur in muscles which are attached to the skeleton.

What characteristics make muscle tissue unique?

Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

Which is the strongest muscle in our body?

The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.

What are some interesting facts about muscles?

Interesting Muscles Facts: Muscles make up about 40% of total body weight. The smallest muscles, like the smallest bones, are found in the middle ear, some of these are the tensor tympani (connected to the ear drum) and the Stapedius. Muscles cannot push, they can only pull.

How many muscles does a human have?

The human muscular system includes three different types of muscles: cardiac muscle (myocardium), smooth muscle and skeletal muscle (or striatum).Our body is made up of about 640 muscles. Without them we can not live.

What is muscle activity?

Muscle activity during the gait cycle The movement pattern that we observe in the lower limbs during walking results from the interaction between external forces (joint reaction and ground reaction) and internal forces (produced by muscles and other soft tissue).

What are muscles for kids?

Kids Definition of muscle. 1 : a tissue of the body consisting of long cells that can contract and produce motion. 2 : an organ of the body that is a mass of muscle tissue attached at either end (as to bones) so that it can make a body part move. 3 : strength of the muscles He doesn’t have the muscle to lift that.
