How to draw internal structure of ear Ear  is the auditory sense organ and also helps in maintaining body equilibrium.  Human ear is divided in to External, Middle and Internal ear. External ear consists of a flap like structure called Pinna. It leads to auditory canal. The pinna is crumpled and is made up of cartilage. Middle ear plays an important role in amplifying the vibrations received on the ear drum. The chain of three bones Malleus, Incus and Stapes helps in amplification of sound. 1. Draw the out line of the ear as well as internal ear as shown.  2. Now focus on drawing Ear drum and three bones Malleus, Incus and stapes as shown. 3.Draw the Cochlea and three semicircular canals as shown.  4. Give double line for Auditory canal and Eustachian tube.  5. Put lot of neat dots around to represent the bone of the skull.   6. Label the parts neatly as shown. cont:-Internal ear consists of bony labyrinth enclosing mem...

How to draw embryo The growing  embryo  forms four membranes-Chorion, Amnion, Allantois and Yolk sac.Chorion establishes connection with the walls of the uterus and helps in the supply of nutrients to the embryo and in the removal of wastes from the embryo. Amnion forms a sac like structure around the embryo. The space between the amnion and embryo is filled with a fluid called Amniotic fluid. Amnion and amniotic fluid give protection to the embryo against mechanical shocks. Amnion is retained till the child is born as the embryo grows the amnion also grows in size. Another sac like structure called Allantois is continuous with urinary bladder of growing embryo. Yolk sac usually supposed to contain reserve food material, but in human embryo it is vestigial and useless. 1.Draw tiny human embryo as shown.  2.Make Amnion around it as shown.  3.Draw Yolk sac and Allantois as shown.  4.Draw one more membrane around as shown, it is Chorion 5.Dra...

How to draw female reproductive system Female reproductive system has muscular elastic bag like structure called Uterus and pair of  ovaries attached to it on either sides.  Uterus opens into vagina through narrow cervical canal.Two tube like structures emerge out of  uterus on either sides. These are called oviducts.We can start with basic shape of Uterus, later we go for oviducts and vagina. Let`s start   the diagram. Step 1: Draw a inverted triangle as shown.  Step 2: Draw out line of uterus around the triangle as shown. Step 3: Erase the inner  triangle as shown. Step 4: Draw a smaller triangle  in the middle. Step 5: Complete the inner structure of uterus by following the triangular shape as shown. Step 6: Define the tip of uterus as shown to represent cervix. Step 7: Draw two tubes  out of uterus on either sides as shown. Step 8: Continue the curved line of uterus along the oviducts as shown. Draw the vagina...

How to draw LS of kidney The LS of  kidney  shows outer dark zone called the cortex and inner pale red zone called medulla which forms the main mass of the kidney. The medulla is made of number of pyramidal structures containing renal tubules or Nephrons projecting into the cavity towards the inner region of kidney called pelvis.This is the region where renal artery and renal vein enter the kidney. Free end of pelvis shows cup like depressions called calyces. Renal pyramids of medulla project into these calyces.Now, lets`s start drawing the diagram. Here we go.   1.Draw a bean shape as shown in figure 2.Erase the depression and make it double lined.   3Draw the Pelvis and ureter coming out of the opening. 4.Mark about seven radiating lines along  the inner  curvature. 5.Draw the renal pyramids as shown along the inner curvature of kidney. 6.Draw Calyces connecting the renal pyramids as shown in f...

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 ...

How to draw Male reproductive system - Front view The male reproductive system consists of a number of sex organs that are a part of the human reproductive process. The sex organs which are located in the pelvic region include a pair of testes along with accessory ducts, glands and the external genitalia.Testes are a pair of oval pinkish male primary sex organs suspended outside the abdominal cavity within a pouch called scrotum. The scrotum helps in maintaining the low temperature of the testes lower than the normal internal body temperature necessary for spermatogenesis.  The testes descend into the scrotum just before birth. The condition in which the tested s do not descent into the scrotum is called cryptorchidism. 1.Draw a urinary bladder with a pair of ureters and Urethra. 2.Now draw Penis over Urethra. 3. The draw Seminal vesicles, Prostate and bulbourethral glands fallowed by inner details of penis. 4. Then draw testes on either sides of Penis. 5.Dr...
