sergejj [24]

The pronunciation of the anatomic structure that conducts impulses to and from the brain and initiates reflex action to sensory information is the spinal cord.

  • The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lowers it back together.
  • Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
  • The protection of the spinal cord, nerve roots, and many internal organs are the spine's three primary tasks. To keep your body upright, give it balance and structural support.
  • Enable fluid movement. The spinal cord is surrounded by cerebrospinal fluid (CSF), which is additionally protected by three layers known as the meninges (dura, arachnoid, and pia mater). The spinal column, which consists of 33 bones known as vertebrae, houses the spinal cord.

almond37 [142]

Answer:

sarcoplasmic reticulum deteriorates and ATP production is stopped

Explanation:

Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state.

Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.
