  2. Interatrial septum - Wikipedia

    en.wikipedia.org/wiki/Interatrial_septum

    Lipomatous atrial septal hypertrophy (LASH) is the fat deposition in the infoldings of the interatrial septum adjacent to the true atrial septum. It is shaped like a “dumbbell” because the deposition is located at the above and the below the fossa ovalis, sparing the fossa itself. The incidence of LASH increases with older age and obesity.

  3. Primary interatrial foramen - Wikipedia

    en.wikipedia.org/wiki/Primary_interatrial_foramen

    The septum primum, a septum which grows down to separate the primitive atrium into the left atrium and right atrium, grows in size over the course of heart development.The primary interatrial foramen is the gap between the septum primum and the septum intermedium, which gets progressively smaller until it closes.

  4. Fossa ovalis (heart) - Wikipedia

    en.wikipedia.org/wiki/Fossa_ovalis_(heart)

    The fossa ovalis is a depression in the right atrium of the heart, at the level of the interatrial septum, the wall between right and left atrium.The fossa ovalis is the remnant of a thin fibrous sheet that covered the foramen ovale during fetal development.

  5. Atrium (heart) - Wikipedia

    en.wikipedia.org/wiki/Atrium_(heart)

    The interatrial septum has an opening in the right atrium, the foramen ovale, which provides access to the left atrium; this connects the two chambers, which is essential for fetal blood circulation. At birth, when the first breath is taken fetal blood flow is reversed to travel through the lungs.

  6. Atrioventricular node - Wikipedia

    en.wikipedia.org/wiki/Atrioventricular_node

    The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles. The AV node is quite compact (~1 x 3 x 5 mm). [2]

  7. Bachmann's bundle - Wikipedia

    en.wikipedia.org/wiki/Bachmann's_bundle

    In the heart's conduction system, Bachmann's bundle (also called the Bachmann bundle or the interatrial band) [1] is a branch of the anterior internodal tract that resides on the inner wall of the left atrium. It is a broad band of cardiac muscle that passes from the right atrium, between the superior vena cava and the ascending aorta. [2]

  8. The Clitoris And The Body - The Huffington Post

    projects.huffingtonpost.com/cliteracy/anatomy

    From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.

  9. Heart - Wikipedia

    en.wikipedia.org/wiki/Heart

    The interatrial septum separates the atria, and the interventricular septum separates the ventricles. [8] The interventricular septum is much thicker than the interatrial septum since the ventricles need to generate greater pressure when they contract.
