Spherical Mirrors

Spherical mirror, as the name suggests, has a sphere-like shape. It appears as if it is a part of a sphere. There are two types of spherical mirrors:

  • Concave Mirror - It is a spherical mirror whose reflecting surface is curved inwards.

  • Convex Mirror - It is a spherical mirror whose reflecting surface is curved outwards.

Anatomy of Human Heart

The heart has a somewhat conical form and is enclosed by the pericardium. It is positioned posteriorly to the body of the sternum with one-third situated on the right and two-thirds on the left of the midline. The heart measures 12 x 8.5 x 6 cm and weighs ~310 g (males) and ~255 g (females)

Relations

  • Anteriorly: the body of the sternum, and adjoining costal cartilages; left lung, and pleura (apex)
  • Posteriorly: oesophagus, descending thoracic aorta, azygos, hemiazygos veins,  and thoracic duct
  • Superficially : bifurcation of the main pulmonary trunk
  • Inferiorly: diaphragm
  • Laterally: lungs, pleura
