Human Anatomy 2

Sense system

Vision tool

Visual apparatus consists of the eyeball, optic nerve, and additional tools eyes.
The eyeball is round, only the front field to deviate from a perfect spherical shape because the cornea is more prominent in the future. This occurs because this section is more curved than in other parts of the eyeball. Front and center point of the field behind the field called the polar front and rear poles.
The connecting line axis is the axis of the eye or visionaries.

eye-balls can be distinguished walls and contents. The walls consist of three layers. The outer layer is the tough membrane, which is in front of the switch becomes cornea. Middle layer called the choroid membrane that lines the hard membrane from the inside. Next to the choroid membrane does not follow the cornea. In place inbetween the choroid and iris membranes are thicker and the shape known as ciliary body. In the middle there is a hole iris called the pupil.

Hearing tools

Hearing aids consist of external listener, the listener and the listener in the middle. Listeners outside consists of the ear and the outer ear canal. The ear is a flap of skin that form the framework of the ear cartilage supple. The outside of the outer ear canal walled-prone, the inside has a bone wall. Next to the outer ear canal is limited by the lining of the cavity gendangan gendangan.

tools consist of a central pendengaranPendengar gendangan cavity associated with the pharynx through the Eustachian tube listener. In gendangan cavity contained the bones of listeners, namely hammer, anvil and stirrup. Gendangan hammer attached to the membrane and with a small joints is also associated with the runway. Grounding into contact with stirrups attached to the membrane that covers the aperture ellipse on the wall in the cavity.

Skin

Skin consists of epidermis and cuticle. Epidermis consists of several layers, the top layer horns are composed of cells flattened, while the innermost layer is called the seed layer that constantly make new epithelial cells.

kulitKulit hides form of connective tissue containing blood vessels and nerves. Cuticle bulge in the form of a finger into the epidermis known as papil cuticle. In it there is blood and lymph capillaries and nerve endings with agencies flavorings.





Digestive System

oral cavity mouth from the slit mouth and ended up in the back of the throat hole. Therefore dental arch, oral cavity is divided into two parts: the porch located outside the dental arch and oral cavity contained in tow. Home bounded to the outside by the lip and cheek muscles containing expression and therefore very broad movement.

teeth
Dentition consists of two rows of teeth closed. Each row of teeth is a curved line on the upper jaw slightly different shape than the lower jaw. Teeth on the upper jaw and the lower jaw is located such that the largest cross-section of each tooth of the upper jaw right occupy interposed between two teeth of the lower jaw and vice versa. So when chewing each tooth cooperating with two opposing teeth lying.

Side

Side is part of the digestive tract that extends like a pouch, terletakdi upper left abdominal cavity, and for the most part covered by tools such as the adjacent liver, colon and spleen. Gastric associated with the devices and also the rear wall of the abdominal cavity through the abdominal coated with several folds.






Urinary system

kidney

Kidney is a bean-shaped gland located at the back wall of the abdominal cavity segments as high as the upper spine, the left kidney is located higher than right kidney. Renal side facing the concave shape. Here the incoming pulse kidneys (from aortic) into the kidney. This nerve branches in the network kidneys.





bladder

The bladder is a gathering place of all urine emanating from the bile duct. Bladder wall consisting of smooth muscle tissue can adapt to the amount of urine in the bladder, because it can be loosened if slowly filled with urine.






Reproductive System

Male reproductive organs
Reproductive organs of men divided into parts makers and parts dealers mani mani. The first part in the form of sex glands, the testicles are formed sperm cells. Right and left testicles hung in a fold of skin in the form of a bag and is located below the bladder pubic bone called the testicles (scrotum). On the back side of each testicle testicles are children classified as a street dealer.

skrotumSel-sperm out of the testicles and into the child's testicles. Here the sperm cells through a fine channels that meander and at the bottom of the child's testicles turned into a seminal pipe, which runs in front of the pubic bone to the top, accompanied by a pulse testicles and woven veins. Scrotum, testicles and straps children seminal covered by some veil and also the muscle layer called pegantung muscle that can pull the scrotum and testicles upwards child.

Female reproductive organs
 
Female reproductive organs consist of the ovaries, uterine tubes, uterus, vagina coitus and outer genitals. Ovary numbered two, located on the side wall of the small pelvis on the right and on the left. Each ovary depends on several folds applaud the connective and stomach. The ovaries are the female sex glands that produce sex cells, ie cells of the egg.

The egg cells in the ovaries shrouded by a veil consisting of cells,
The overall form of the form of the so-called follicle or Graaf bubbles. In women who have sex ripe, a developing follicle bulge on the surface of the ovaries, which resembles the surface of the fruit srikaya. After the follicles mature, it will burst, throwing out the egg cells are now floating in the abdominal cavity (this event is called ovulation).

Nervous System

brain
Developing central nervous system of a tube-shaped structure. On the tube can be seen a basic, a roof and two walls of a canal side as a barrier located in the middle. In a further development in some places had become thick tube, while in other places the walls remain as before.

brain booth front of developing two symmetric bubble located. The bubbles then becomes both hemispheres of the cerebrum. On the rear side of the brain is formed small, therefore the roof the roof here are becoming increasingly bold.


Spinal cord

Spinal cord stem resembles the cross-section kelubi jorong. It is located in the spinal canal anatara cranial cavity and waist area. Cross-section from top to bottom getting smaller, except in two places, namely in the area of the neck and in the lumbar region. In these places spinal cord is rather wide.








Endocrine system

glands Himofise
Himofise gland is an endocrine gland located at the base of the skull, in the pituitary fossa spenoid bone. Himofise gland plays an important role in the secretion of hormones from all endocrine organs because it produces hormones that can influence the activity of other glands.

Thyroid gland
tiroidKelenjar thyroid consists of two sides that is located to the right of the trachea tied together by a network of crossing the thyroid and trachea at the front. The thyroid gland is a gland located in the lower front of the neck, attached to the wall of the base of the throat.
