nlexa [21]

Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.

Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.  

Weak contraction

  • Potassium accumulates in the sarcoplasm.
  • Contracted lower sarcoplasm pH.
  • Begin contraction with muscle already 50%.
  • The circular arrangement of muscle fascicles.

Stronger contraction

  • Increase in muscle belly circumference.
  • A lesser proportion of motor neurons to muscle fibers.
  • Increased recruitment.
  • Increased stimulus frequency.

Nutka1998 [239]

The commonly used site to feel a pulse is radial artery on the wrist, the point where radial artery approaches the wrist present at the middle of wrist.

When we placed our fingers in the middle of wrist, we can feel the pulse wave. That is  72 beats per minutes. The radial artery is the site of insertion of the arterial line, for monitoring the blood pressure. It is selected because it is accessible due to the low incidence of the complications such as thrombosis.

The pressure of the blood is always high in the arteries comparative to the veins, usually arteries are present deep in the body, the radial artery in only artery that approaches the skin. Hence, it is used to monitoring the pulses.
