This video presentation shows a method of harvesting the two most important highly vascular structures that support forebrain function. They are the cerebral surface (superficial) vasculature along with associated meninges (MAV) and the choroid plexus which are necessary for cerebral blood flow and cerebrospinal fluid (CSF) homeostasis.

Micro-dissection of rat brain into various regions is extremely important for the study of different neurodegenerative diseases. This video demonstrates micro-dissection of four major brain regions include olfactory bulb, frontal cortex, striatum and hippocampus in fresh rat brain tissue. Useful tips for quick removal of respective regions to avoid RNA and protein degradation of the tissue are given.

The major pelvic ganglia contain parasympathetic and sympathetic neurons that innervate pelvic organs. Here we describe a dissection method and provide schematics for identification of these ganglia and their associated nerves. These methods can be applied to experimental manipulation of these ganglia in vivo or removal post-mortem for further study.

Understanding enamel formation and possible alterations requires the study of ameloblast activity. Here, we describe a reliable and consistent method to micro-dissect enamel organs containing secretion- and maturation-stage ameloblasts that may be used for further quantitative and qualitative experimental procedures.

We present a method to isolate the adult organ of Corti as three intact cochlear turns (apex, middle, and base). We also demonstrate a procedure for immunostaining with fluorescently tagged antibodies. Together these techniques allow the study of hair cells, supporting cells, and other cell types found in the cochlea.
FAQs
The method allows investigators to examine how organ position, morphology, and size vary across life stages. These anatomical differences provide observable evidence for changes in organ formation, growth, and functional integration. By relating visible structure to developmental stage, students and researchers can interpret how vertebrate organ systems become increasingly organized rather than viewing anatomy as a fixed arrangement.
Maintaining the spatial relationships among organs helps investigators interpret anatomy in context. Position and adjacency can be documented alongside morphology and size, making observations more meaningful than isolated descriptions of individual tissues. This approach supports structure-function interpretation and improves comparisons among specimens or life stages by showing how organs are arranged within the body.
Organ position, overall morphology, and relative size provide the main observations for developmental comparisons. Recording these features systematically can reveal how body regions and organ systems change as rats grow. In developmental biology, such comparisons help organize evidence about organ formation, growth, and the progressive integration of systems across successive life stages.
A systematic workflow proceeds from examining body regions to making incisions, separating tissues, exposing internal structures, and observing the resulting anatomy. Investigators should preserve anatomical relationships while progressing through these stages, then document features such as organ position, morphology, and size. Following an ordered sequence makes observations more consistent and supports clearer interpretation of the specimen.
Documentation should record identifiable anatomical features and their relationships, including organ position, morphology, and size. Notes or other scientific records can be organized by body region and linked to the developmental stage being examined. Clear documentation strengthens anatomical identification, allows comparisons across specimens, and provides a basis for interpreting structure-function relationships.
It is particularly useful when investigators need direct anatomical comparisons across life stages or want to examine how organ systems form, grow, and become functionally integrated. The procedure also provides practical training in anatomical identification and scientific documentation. These capabilities support broader vertebrate research by connecting observable anatomy with developmental patterns and structure-function interpretation.
