Metaphase and Anaphase
Upon entry into anaphase, the mitotic spindle reorganizes dramatically: kinetochore fibers attached to chromosomes shorten, bringing chromatids toward the poles. The astral microtubules, which radiate from each spindle pole, elongate until they reach the cell surface. Meanwhile, a bundle of antiparallel microtubules, called the ‘central spindle,’ remains at the midpoint between the two poles. The central spindle and astral microtubules collaborate to position the division plane during cytokinesis.

Mossy fibers, which are one major type of axon in the cerebellum, relay information from outside the cerebrellum. Here multicolored mossy fibers fan within the inner granular layer of one fold or “gyrus” of the cerebellum. The enlarged “splotches” of color represent presynaptic terminals, called mossy fiber rosettes. Around the edge of the gyrus, the parallel fibers course through the molecular layer where they synapse onto Purkinje cell dendrites (not visible).

MRI is the investigative tool of choice for neurological cancers as it is more sensitive than CT for small tumors and offers better visualization of the posterior fossa. The contrast provided between grey and white matter make it the optimal choice for many conditions of the central nervous system including demyelinating diseases, dementia, cerebrovascular disease, infectious diseases and epilepsy.

The sinus venosus is a large quadrangular cavity which precedes the atrium on the venous side of the chordate heart. In mammals, it exists distinctly only in the embryonic heart (where it is found between the two venae cavae). In the embryo, the thin walls of the sinus venosus are connected below with the right ventricle, and medially with the left atrium, but are free in the rest of their extent. It receives blood from the vitelline vein, umbilical vein and common cardinal vein. It originally starts as a paired structure but shifts towards associating only with the right atrium as the embryonic heart develops. The left portion shrinks in size and eventually forms the coronary sinus (right atrium) and oblique vein of the left atrium, whereas the right part becomes incorporated into the right atrium to form the sinus venarum.
