The disorders of the CNS
Introduction on CNS injury The CNS consists of neurons that receive, store & send information, & despite their specialized functions, there are still a growing number of injuries that affect the CNS. The types of CNS injuries include: Acute neuronal injury (red neurons); subacute & chronic neuronal injury (degeneration); motor axons damage; neuronal inclusions; proteinopathies. Read more

The disorders of the bones & musculoskeletal system
Introduction The bones, ligaments, cartilages and muscles are important components of the musculoskeletal system. Together, they’re responsible for the shape, size of the body; motion; visceral organ protection & hematopoiesis, particularly in bones. The layers of the bone include the periosteum & endosteum. Within the bones are: osteoid (unmineralized organic matrix); mineral calcium hydroxyapatite; osteoprogenitor Read more

How proper study of the brain uncovers its parts
Introduction The brain receives sensory information and controls activities of the trunk, and also limbs through its connections with the spinal cord. Within the brain are 12 pairs of cranial nerves that interact with regions of the head and face. The division of the human brain consists of: rhombencephalon (hindbrain); mesencephalon (midbrain); prosencephalon (forebrain). Rhombencephalon Read more

The best way to understand the spinal cord
Introduction The spinal cord and the brain make up the CNS in which there are neuronal cell bodies in large numbers. Within the CNS are also the grey and white matter. The grey matter consists mainly of a group of cell bodies with dendrites and synaptic junctions. Within the white matter are a collection of Read more

Our neurons and how interesting Neuroscience is
Introduction Neuroscience is a delicate aspect of science about neurons that equally combines other areas of Neuroanatomy and Neurophysiology. It brings to focus a broad knowledge about the human nervous system which is complex. Ongoing research about known and unknown diseases of the nervous system enables accurate therapy and advancing technologies that save lives. The Read more

Other white cell disorders you should know and Hodgkin lymphoma
Lymphoplasmacytic lymphoma This is a tumor of mature B-cells, in which these tumor cells differentiate largely into immunoglobulin M producing plasma cells. It usually affects people between 60 & 70 years of age. Histologically, these neoplastic plasma cells contain Russell bodies (Cytoplasmic Ig) & Dutcher bodies (nuclear Ig) on periodic acid-Schiff stain. The cause is Read more
