Coronal Section of a Fetal Brain
Coronal section of a fetal brain, approximately 21 weeks gestational age, with edema. Notice how, unlike in adult brains, there is no apparent delineation between white matter and grey matter due to incomplete myelination of the immature brain.

Ependymoma
A common histologic finding in ependymomas (shown here) are perivascular pseudo-rosettes characterized by neoplastic ependymal cell nuclei radiating outward from a blood vessel, which creates a pink zone of glial processes immediately surrounding the blood vessels.Â

Pilocytic Astrocytoma
Stemming from the Latin word "Pilos", meaning "resembling or composed of hair", pilocytic astrocytomas are named as such because of their long hair-like gliofibrillary processes (clear arrows) that stem off of slender bipolar nuclei (black arrows), which are best seen on smear preparation of fresh tissue (depicted here).

Anatomy of the Human Eye
The Human eye is divided into two main regions: 1. the vitreous humor-filled vitreous body (bottom of image), and 2. the anterior chamber (top of image), which is bordered by the cornea anteriorly (very top of image) and the iris & lens posteriorly (mid-horizon of image). The disc-shaped lens is typically optically clear to allow... Continue Reading →
