The semilunar hiatus (eg, hiatus semilunaris) is a crescent-shaped [citation needed] /semicircular/ [1] curved [2] slit [2] /groove [1] upon the lateral wall of the nasal cavity [3] at the middle nasal meatus just inferior to the ethmoidal bulla. [2] It is the location of the openings for the frontal sinus, maxillary sinus, and anterior ...
The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta.It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve.
Through the hiatus semilunaris the meatus communicates with a curved passage termed the infundibulum, which communicates in front with the anterior ethmoidal cells and in rather more than fifty percent of skulls is continued upward as the frontonasal duct into the frontal air-sinus; when this continuity fails, the frontonasal duct opens ...
The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
This subdivisions is a local level of government beneath the provincial level. However, they enjoy greater decentralisation of affairs than the provincial body, such as provision of public schools and public health facilities. They were formerly known collectively as Daerah Tingkat II (Level II Region). [14]
The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery, and has three cusps.
A Spigelian hernia is the type of ventral hernia that occurs through the Spigelian aponeurosis, which is the part of the aponeurosis of the transverse abdominal muscle bounded by the linea semilunaris (or Spigelian line) laterally and the lateral edge of the rectus abdominis muscle medially.
The trigeminal ganglion contains cell bodies of the pseudo-unipolar sensory neurons of the trigeminal nerve which extend their axons both distally/peripherally into the three divisions of the trigeminal nerve on the one end, and proximally/centrally to the brainstem on the other end; the trigeminal root extends from the trigeminal ganglion to the ventrolateral aspect of the pons.
