Resumen del Recurso

Pregunta 1

Respuesta
  • pericardial cavity
  • fibrous pericardium
  • parietal serous pericardium
  • visceral serous pericardium
  • pericardial sac
  • epicardium
  • endocardium
  • myocardium

Pregunta 2

Pregunta
Functions of pericardium
Respuesta
  • Facilitation of secure intrathoracic cardiac stability
  • Friction reduction between heart & the mediastinum structures
  • Nutrition of the heart
  • Limitation of cardiac distention and chamber dilation
  • Uniform cardiac distribution of pericardial cavity hydrostatic pressure
  • Formation of a barrier to stop infection
  • Facilitation of atrial filling by promoting negative pericardial pressure during ventricular systole
  • (pericardium + pleural fluid): formation of a system that automatically applies compensating hydrostatic pressures to the cardiac periphery when accelerating forces act

Pregunta 3

Pregunta
The thickness of the pericardium is [blank_start]1-2 mm[blank_end].
Respuesta
  • 1-2 mm

Pregunta 4

Pregunta
Fibrous pericardium
Respuesta
  • made up from tough connective tissue
  • thick
  • thin
  • stong
  • fragile
  • composed mainly of three collagen layers, cross-woven at 150° to each other

Pregunta 5

Pregunta
Pericardial relationships Anteriorly: [blank_start]lungs[blank_end] + [blank_start]pleura coverings[blank_end] Laterally: [blank_start]pleural coverings[blank_end] of the mediastinal surfaces of the lungs Superiorly: [blank_start]diaphragm[blank_end]
Respuesta

Pregunta 10

Pregunta
Adult weight is achieved between the ages of [blank_start]17[blank_end] and [blank_start]20[blank_end] years. The heart reaches 50% of its adult dimensions [blank_start]at birth[blank_end], 75% by [blank_start]5[blank_end] years and 90% by [blank_start]12[blank_end] years
Respuesta

Pregunta 11

Pregunta
-The extensive [blank_start]interatrial groove (of Waterston)[blank_end] separates the two atria. -The [blank_start]atrio- ventricular (coronary) groove[blank_end] separates the atria from the ventricles and contains the main trunks of the coronary arteries. -Internally, the ventricles are separated by the septum; its mural margins correspond to the ante- rior and inferior (diaphragmatic) [blank_start]interventricular grooves[blank_end].
Respuesta
  • interventricular grooves
  • atrio- ventricular (coronary) groove
  • interatrial groove (of Waterston)

Pregunta 12

Pregunta
The apex of the heart is located most commonly behind the [blank_start]fifth left[blank_end] intercostal space, near or a little medial to the [blank_start]midclavicular line[blank_end].
Respuesta
  • fifth left
  • midclavicular line

Pregunta 13

Pregunta
The diaphragmatic surface of the heart rests mainly on the [blank_start]central tendon[blank_end] but also, apically, on a small area of the left muscular part of the diaphragm.
Respuesta
  • central tendon
