How to draw Sagittal section of Human brain

Brain is the site of information processing and control. It is protected in the cranial cavity and covered by three connective tissue membranes called Cranial meninges.The brain can be divided into three major parts called i. Fore brain ii. Mid brain iii. Hind brain. Fore brain consists of Olfactory bulb, Cerebrum and Diencephalon. Mid brain is locateb between the thalamus of the fore brain and the Pons Varoli of the hind brain. Hind brain comprises Cerebellum, Pons varoli and Medulla oblongata.  Cerebellum is the second largest part of the brain. It consists of two Cerebella hemispheres  It has  branching tree -like core of white mater called Arbor vitae (the tree of life) surrounded by a sheath of grey matter.


1.Draw  an inverted bean shape.

















2.Draw Corpus callosum and other regions of the brain as shown in the bean shape.
 3.Then make brain stem and Cerebellum as shown.
 4.Make the grooves on cerebrum as shown.






















 The brain consists of four ventricles. The first and second ventricles (Paracoels) are present in the right and left cerebral hemispheres respectively. The third  ventricle (Diocoel) occurs in the diencephalon. The two Paracoels are connected to the median diocoel individually by the two foramina of Monro. The fourth ventricle (Myelocoel) is present in the medulla . The myelocoelk and the diocoel are connected by a narrow canal caller iter or Aqeuduct of Sylvius/Cerebral aqueduct..The ventricles of the brain, and the subarachnoid space are filled with Cerebro- spinal fluid. CSF is an alkaline, colourless fluid which is filtered from the choroid plexuses into the ventricles of the brain.

How to draw Nephron Each kidney is made of about one million single units called nephrons. These are the structural functional units of the kidney and concerned with separating urine from the blood. Each nephron is made of two main parts called malpighian body and covoluted tubule.Malphigian body is double layered cup also called bowman`s capsule. The inner cup consists network of capillaries called Glomerulus.                                    Now let`s start the diagram. 1.Draw a egg shape and  make a folded curve as shown in the figure and     attach it to a vertical line. 2. Draw double line along the curve and draw Glomerulus as shown in the      bowman`s capsule. 3. Draw the capillary network as shown in the fi...

How to draw skin LS Our  skin  is the sense organ for touch. It contains cutaneous receptors for touch. The skin consists of two main layers called epidermis and dermis. Epidermis is the layer for protection. It has outer stratum corneum or cornified layer containing dead cells, middle granular layer containing living cells and inner malpighian layer containing the cells dividing constantly.  Dermis lies below the epidermis. It is made up of elastic connective tissue. It contains sweat glands, sebaceous glands, hair follicles, blood vessels and fat. Here we start the diagram. 1.Draw a cuboid shape as shown.  2.Draw the epidermis and endodermis as shown.  3.Draw hair follicles and other details of the skin as shown.  4. Label the parts as shown.
