Перечный срез спинного мозга typically consists of white matter on the outside and grey matter on the inside. White matter is made up of myelinated nerve fibers, while grey matter contains cell bodies and unmyelinated fibers. The grey matter is arranged in a butterfly-shaped pattern called the grey horn, with sensory neurons located in the dorsal horn and motor neurons in the ventral horn.

Клетки крови include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Erythrocytes are responsible for carrying oxygen to tissues, leukocytes are involved in the body's immune response, and thrombocytes help in blood clotting. Different types of leukocytes include neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specific functions in the immune system.

Костная ткань is a dense and hard connective tissue that provides support and protection to the body. It is composed of two main types of bone tissue: compact bone (cortical bone) and spongy bone (cancellous bone). Compact bone is found on the outer surface of bones and is dense and strong, while spongy bone is located in the interior and is more porous and lightweight. Osteoblasts are responsible for bone formation, while osteoclasts break down old bone tissue. Bone marrow, located within bones, produces blood cells and stores fat.
