Optic nerve hypoplasia (ONH) is a congenital condition in which the optic nerve is underdeveloped (small). Many times, de Morsierâs Syndrome or septo-optic dysplasia (SOD) is associated with ONH, however, it is possible to have ONH without any additional issues like SOD.
Pyramidal neurons (pyramidal cells) are a type of neuron found in areas of the brain including cerebral cortex, the hippocampus, and in the amygdala.Pyramidal neurons are the primary excitation units of the mammalian prefrontal cortex and the corticospinal tract.eatures Edit. One of the main structural features of the pyramidal neuron is the triangular shaped soma, or cell body, after which the neuron is named. Other key structural features of the pyramidal cell are a single axon, a large apical dendrite, multiple basal dendrites, and the presence of dendritic spines.
In this type of plasma cell neoplasm, the abnormal plasma cells (myeloma cells) are in one place and form one tumor, called a plasmacytoma. Sometimes plasmacytoma can be cured. There are two types of plasmacytoma.lasma cell neoplasms are diseases in which abnormal plasma cells or myeloma cells form tumors in the bones or soft tissues of the body. The plasma cells also make an antibody protein, called M protein, that is not needed by the body and does not help fight infection.
