The acetabulum is also home to the acetabular fossa, an attachment site for the ligamentum teres, a triangular, somewhat flattened band implanted by its apex into the antero-superior part of the fovea capitis femoris. The notch is converted into a foramen by the transverse acetabular ligament; through the foramen nutrient vessels and nerves ...
There are two important foramina, or windows, two important fissures, or grooves, and one canal surrounding the globe in the orbit. There is a supraorbital foramen, an infraorbital foramen, a superior orbital fissure, an inferior orbital fissure and the optic canal, each of which contains structures that are crucial to normal eye functioning.
Orbital septum acts as a physical barrier that prevents the infection of the anterior part of the eye spreading posteriorly. For example, preseptal cellulitis mainly infects the eyelids, anterior to the orbital septum. Meanwhile, orbital cellulitis is located posterior the orbital septum, due to infections spreading from the ethmoidal sinuses.
the fibular region encompassing the outside of the lower leg, the tarsal region encompassing the ankle, the pedal region encompassing the foot; the digital/phalangeal region encompassing the toes. The great toe is referred to as the hallux. The regions of the upper limbs, from superior to inferior, are the axillary region encompassing the ...
The septal area is located on the lower posterior part of the frontal lobe. The septal area refers to the nearby septum pellucidum. It is located underneath the corpus callosum and in front of the lamina terminalis. The lamina terminalis is a layer of gray matter that connects the optic chiasma and the anterior commissure. [7]
It is located beneath the frontal bones and in front of the sphenethmoid, and articulates with the interorbital septum anteriorly. The mesethmoid is composed of a horizontal dorsal plate located directly beneath the frontals from which a median septum (a thin wall of bone at the skull midline) extends ventrally to make contact with the ...
Excretory bladders are located at posterior end of the cercarial body. The metacercarial cyst is elongated and oval-shaped with sensory papillae. The excysted metacercarial is oval-shaped with a subterminal sucker and a ventral sucker. The adult form of P. gralli is fusiform shaped. Body surface is covered by small spines at acetabular region.
In flatworms, acetabulum is the ventral sucker situated towards the anterior part of the body, but behind the anterior oral sucker. It is composed of numerous spines for penetrating and gripping the host tissue. The location and structure of the acetabulum, and the pattern of the spine alignment are important diagnostic tool among trematode ...
