This is a different kind of arteriosclerosis. This is hyperplastic arteriolosclerosis, which most often appears in the kidney in patients with malignant hypertension. The arteriolar wall is markedly thickened and the lumen is narrowed.

Arteriosclerosis, or "hardening of the arteries" is a generic term that includes atherosclerosis, arteriolosclerosis, and medial calcific sclerosis.

Herpangina, also called mouth blisters, is the name of a painful mouth infection caused bycoxsackieviruses. Usually, herpangina is produced by one particular strain of coxsackie virus A (and the term "herpangina virus" refers to coxsackievirus A)[1] but it can also be caused by coxsackievirus B or echoviruses.[2] Most cases of herpangina occur in the summer,[3]affecting mostly children. However, it occasionally occurs in adolescents and adults. It was first characterized in 1920

The Bile Solubility Test

Bile will selectively lyse colonies of Streptococcus pneumoniae while other strep are immune to bile's activity. When a bile salt such as desoxycholate is added directly to Streptococcus pneumoniae growing on an agar plate or in a broth culture the bacteria will lyse and the area become clear. Other alpha-hemolytic streptococci are resistant to (not lysed by) bile and will stay visible or turbid (cloudy).

A pituicyte is a glial cell of the posterior pituitary.

They generally stain dark purple, and are among the easiest structures to identify in the region (pars nervosa of the posterior pituitary). [1][2]

They are similar to the astrocytes/glial cells of the CNS.

THE DEEP INGUINAL RING IS ASSOCIATED WITH INDIRECT INGUINAL HERNIA!

File:Inguinal fossae.PNG
The medial inguinal fossa is a depression located within the inguinal triangle on the peritoneal surface of the anterior abdominal wall between the ridges formed by the lateral umbilical fold and the medial umbilical ligament, corresponding to the superficial inguinal ring.

There are two major classes of herniation: supratentorial and infratentorial. Supratentorial herniation is of structures normally above the tentorial notch and infratentorial is of structures normally below it.[4]

  • Supratentorial herniation
  1. Uncal (transtentorial) NOTE: TEMPORAL LOBE MOST FREQUENTLY INVOLVED
  2. Central
  3. Cingulate (subfalcine)
  4. Transcalvarial
  • Infratentorial herniation
  1. Upward (upward cerebellar or upward transtentorial)
  2. Tonsillar (downward cerebellar)

  • The prevertebral fascia (encloses the vertebral region of the neck)
