EMBOLISM:

  • The obstruction of a blood vessel by a foreign substance or a blood clot that travels through the bloodstream, lodging in a blood vessel, plugging the vessel. Blood clots are the most common causes of embolisms.
  •  A pulmonary embolus is a blood clot that has been carried through the blood into the pulmonary artery (the main blood vessel from the heart to the lung) or one of its branches, plugging that vessel within the lung.
  • The clots block blood flow to the lungs, pulmonary embolism can be life-threatening.

THE CENTRAL NERVOUS SYSTEM:

  • The central nervous system consists of the brain and spinal cord. The brain plays a central role in the control of most bodily functions, including awareness, movements, sensations, thoughts, speech, and memory. Some reflex movements can occur via spinal cord pathways without the participation of brain structures.
  • The spinal cord is connected to a section of the brain called the brainstem and runs through the spinal canal. Cranial nerves exit the brainstem.
  • Nerve roots exit the spinal cord to both sides of the body.
  • The spinal cord carries signals (messages) back and forth between the brain and the peripheral nerves.

Insertion:
Palpebral part: into the skin of the eyelids, blending with levator palpebrae superioris and continuing on to the lateral palpebral raphe.
Orbital part: into the skin surrounding the orbit and blending with adjacent facial muscles
Action: Closes the eyelids
Innervation: Temporal and zygomatic branches of the facial nerve (cranial nerve VII)
Blood Supply: Branches from the ophthalmic artery

ANEMIA:

  • Anemia is a medical condition in which the red blood cell count or hemoglobin is less than normal. Anemia is caused by either a decrease in production of red blood cells or hemoglobin, or an increase in loss (usually due to bleeding) or destruction of red blood cells.
  • For men, anemia is typically defined as hemoglobin level of less than 13.5 gram/100 ml and in women as hemoglobin of less than 12.0 gram/100 ml.

1.Pasteurisation:

Pasteurisation is a process that slows down microbial growth in food. The aim of pasteurization is not to completely destroy all pathogenic micro-organisms in foods typically in milk & milk products. Just to reduce the number of viable pathogens so that they are unable to cause disease if the pasteurized product is stored as indicated and consumed before its expiry date.

COLOSTOMY:

  • A colostomy is a surgical procedure that brings one end of the large intestine out through the abdominal wall. During this procedure, one end of the colon is diverted through an incision in the abdominal wall to create a stoma.
  •  A stoma is the opening in the skin where a pouch for collecting feces is attached.
  • People with temporary or long-term colostomies have pouches attached to their sides where feces collect and can be easily disposed.
