Answer: Fibrous pericardium and Serous Pericardium

This layer is the most superficial layer which consists of dense connective tissue. This layer of the heart protects it from over filling of blood, anchors the heart to the surrounding wall.

Serous pericardium

The spouse of a client who was struck by lightning asks the nurse why the areas involved seems so small but the damage is extens

Electrical burns usually follow an internal path.

<h3>What are the damages caused by a lightning strike on humans?</h3>

While only 10% of those who are struck by lightning die, many of the 90% who do survive have long-term difficulties.

Depending on the sort of lightning hit and the amount of electricity passing through the body, several effects might result from a lightning strike.

Lightning can destroy tissue, leave deep wounds, and result in skin burns. Additionally, the electrical current may result in a sort of scaring called Lichtenberg figures (branching electric discharges). Unusual fractal patterns emerge as a result of blood vessel destruction that occurs when the lightning current passes through the body to describe this sort of scarring.

A lightning strike can halt the heart, leading to cardiac arrest. It may also result in pulmonary edema and arrhythmias.

Brain injury and a variety of neurological disorders may be brought on by lightning strikes. A person may suffer from spinal cord injuries, go into a coma, feel pain, numbness, or weakness in their limbs, or have sleep or memory issues.

A lightning strike could harm the ear and impair hearing. Additionally, it may result in blindness, corneal damage, and vertigo.
