Clinical significance
Goblet cell carcinoids are a class of rare tumors that form as a result of an excessive proliferation of both goblet and neuroendocrine cells. The majority of these tumors arise in the appendix and may present symptoms similar to the much more common acute appendicitis.The main treatment for localized goblet cells tumors is removal of the appendix, and sometimes removal of the right hemicolon is also performed.Disseminated tumors may require treatment with chemotherapy in addition to surgery.

Goblet cells may be an indication of metaplasia, such as in Barrett's esophagus.

Most lateral deep cerebellar nucleus is:

a. Emboliform nucleus
b. Dentate nucleus
c. Globose nucleus
d. Fastigial nucleus

 

From lateral to medial, the four deep cerebellar nuclei are the dentate, emboliform, globose, and fastigii. Some animals, including humans, do not have distinct emboliform and globose nuclei, instead having a single, fused interposed nucleus. In animals with distinct emboliform and globose nuclei, the term interposed nucleus is often used to refer collectively to these two nuclei.

Which of the following is decussated in superior medullary velum?

d. 6th nerve

Superior medullary velum

From Wikipedia, the free encyclopedia

Superior medullary velum
Coronal section of the pons, at its upper part. (Ant. med. velum labeled at center top.)
Anterior view of the cerebellum. (Ant. medullary velum labeled at center top.)

The superior medullary velum (anterior medullary velum, valve of Vieussens) is a thin, transparent lamina of white matter, which stretches between the superior cerebellar peduncles; on the dorsal surface of its lower half the folia and lingula are prolonged.

It forms, together with the superior cerebellar peduncle, the roof of the upper part of the fourth ventricle; it is narrow above, where it passes beneath the facial colliculi, and broader below, where it is continuous with the white substance of the superior vermis.

A slightly elevated ridge, the fraenulum veli, descends upon its upper part from between the inferior colliculi, and on either side of this the trochlear nerve emerges.

Blood is supplied by branches from the superior cerebellar artery.

The trochlear nerve is unique among the cranial nerves in several respects. It is the smallest nerve in terms of the number of axons it contains. It has the greatest intracranial length. Finally, it is the only cranial nerve that exits from the dorsal aspect of the brainstem.

Which is a typical intercostal nerve?

a. First
b. Second
c. Third
d. Seventh

Intercostal nerves can be divided into atypical and typical intercostal nerves:

• atypical
  • first two intercostal nerves (T1 and T2) in addition to supplying the thorax also give branches to the brachial plexus
  • lowest five intercostal nerves (T7-T11) also supply the abdomen and peritoneum
• typical
• the remaining intercostal nerves (T3-T6) supply only the the thoracic wall

Ans c. THIRD

Basic division of anatomical segments of liver are all except:

a. Hepatic artery
b. Hepatic vein
c. Portal vein
d. Bile duct




b. Hepatic vein

Torus aorticus

The torus aorticus is the prominent region of the right atrial septum sited superiorly and anteriorly. It is superior to the coronary sinus and anterior to the fossa ovalis. It represents the deeper and anterior surface of the posterior sinus and cusp of the aorticvalve.

HEPATIC HILAR AREA: THE PLATE SYSTEM

 The plate system consists of bile ducts and blood vessels
surrounded by a sheath that is continuous with Glisson’s
capsule, intrahepatically, and the hepatoduodenal
ligament, extrahepatically. This system also contains a
large number of lymphatics, nerves, and a small vascular
network. 
Couinaud  states that the bile ducts and
hepatic artery are located within the plate system, but
that the portal vein is covered with a separate sheath
of loose connective tissue, and that is why the plate
containing the extrahepatic bile duct and hepatic artery
can be easily separated from the portal vein. Three
plates are found in the hilar area: the hilar plate, the
cystic plate, and the umbilical plate
