General Structure of the chest, chest Structure
Thoracic vertebrae, ribs and sternum, collectively, the skeleton of the chest (rib cage), they do.
External appearance; chest cage, a little flattened from front to back below the base shape of a cone, front, rear, two side faces has a base and a topping.
Pre-face, from top to bottom and back slightly bent forward, this face width increases gradually from top to bottom. This is in the middle of sternum and ribs and cartilage on the sides with the front ends of the ribs are 1 to 9 th.
The rear face, in the middle of the spine and the spine protrusions, grooves on the sides spine, ribs and rib angle of the rear ends of shows.
Side faces, the ribs are convex partitions between the front and rear angles gradually widens and then narrows as shown by the seventh rib.
Base of the rib cage, from front to back, in the middle hançersi ledge, sides, front ends of the ribs 7 to 10 th of cartilage in combination with each other from the edges, the ribs of the belt name kenar'ar, 11 th ribs from the front end, the 12 th and 12 th ribs from the lower edge of the chest limited to the vertebrae.
Looks at the base of the rib cage down and forward. Shown in front of the angle of the base peak, which is called Charpy angle is 70-75 degrees. The side edges of the angle of Article 7 to 10 ribs are made of cartilage, the ribs are nothing more than the belt.
The medium diameter of the rib cage from front to back base 12, transverse diameter 26 cm. dir.
Chest Hill, was cut, leading incisuru jugularis, the sides of the first rib, the rear is limited to the first thoracic vertebrae. Large diameter, elliptical cross this hole, protrude into the rear edge of the first thoracic vertebrae, chest forward and down direction of the cut at the top is curved elliptical hole. Medium diameter of 6 cm from front to back. transverse diameter of 10 cm. long.
Interior view, inside the walls of the chest cavity, facing the side of the rib cage in this space makes the bones. Here:
1) the backbone of his chest, back, and protruding in the form of the middle column.
2) involving the chest cavity organs, concave on the sides of two large wall that faces the inner ribs, the ribs of them, leading from the back of the sternum occurred.

First, Second, Eleventh and Twelfth Ribs
First Rib
The short ribs are all up and down the wide and somewhat flat, up one so the other one down her face, is one of the edges are convex outward, the other is concave facing inward. The upper side facing upward and slightly forward, and her middle a little bit in front of the ledge near the inner edge is called a Lisfranc tubercle, anterior scalene muscle on the sticks. Two on the ledge in front of and behind the wide but shallow grooves. Piyeste, in arakadaki arter'a subclavian subclavian vena cava is located in the front. Sulcus costae ribs at the rear end like this is not the top down başçık a somewhat flat surface and neck.
Second Rib
The ribs are curved faces, such as how the first horizontal nor vertical, like the others. Outer side face of the rough surface towards the middle of the second rib pürtüğü (tuberosity costae secunda) is called here the middle and rear skalenler that sticks. These ribs do not costae in sulcus.
Eleventh and Twelfth Ribs
In these, such as whether the rib tubercle başçıklarında alone has a joint surface. Article 12 of the ribs from the rib groove, nor what is the angle of the ribs. This latter is very different length of the ribs, as well as 14 cm is too short. as possible.
Ossification; primitive points of the ribs, such as vertebrae, 50 to 60 th day of intrauterine life, body 2 / 3 with the front part 1 / 3 appears on the back part.
Secondary points are başçıkta tubercles and Article 16 the right age develops.
Cartilage ribs, ribs, cartilage, bone, the front ends of ribs are present, they are flattened from front to back, the front face of a convex to a concave rear face, top and bottom two edges, an inner end at the outer end of a show. The latter is embedded in a hollow in the front end of the bone ribs.
The inner ends of the first seven ribs from the sternum cartilage and joints do 8, 9, 10 unculardan merge with one in each upper rib cartilage. 11, 12 ncilerin the free inner ends of the cartilage ribs fazlalaşır lengths up to seventh from the first, then decreases.
Cartilage ribs are different directions in the second and third even though they are just the first cross-over and is curved inward and outward over the others.

What is Thoracic - Sternum sternum
Skeleton Chest, Thorax Online, Thorax Anatomy
The skeleton, the chest in front of the cage-shaped part of the vertebrae.
There are three sections in this piece, also called chest:
1) Thoracic vertebrae
2) Ribs
3) breast bone
Breast bone, sternum is
Sternum, rib cage in front of the center line from front to back on the flat 15 to 20 cm. long, dagger-shaped bone.
Slightly tilted back to front from top to bottom direction of the two ends of the bones of the entire upper and lower edge of the front and rear side there are two sides of the two.
Sternal, as a primitive consists of separate parts called sternebra. These are combined with each other during the development of bone, in the end, that is, in the age of adulthood is in three parts. According to the bone fragments of the dagger in them:
1) Handle
2) Body
3) Sternum'un hançersi tip or protrusion is called.
Furthermore, these three parts: praesternum, mesosternum, also called onphis-ternum.
Dimensions, is the first part of the bone 5-6 cm at its widest point. dir. Average 10-20 mm in thickness than the upper parts. dir.
Pre-face, top to bottom, this percentage is convex, joins with each other showing sternebraların marks are nothing more than a non-transverse crest. Smack into the top ridge line of the merger between body forward at an angle that it makes the angle of Louis Sterne) is called. (Smack between the joint body called symphysis Sterne is also the junction of these two parts is seen in the elderly.)
Sides of the front face above the surface rough-kleido sterno - mastoid muscle m below pectoralis major sticks.
Rear face, this face is concave pürtüksüzdür, transverse crest on the more uncertain.
The side edges, each notch on the edge of seven ribs (incisura Costales) shows that they do joint with seven rib cartilage.
There are six notches in the ribs from among them, getting contracts in the latter from the top down.
Upper-end, the base of the bone in the middle of these extremes, the two sides are three notches. Incisura jugularis Konkavlığı upturned middle notch; konkavlığı side notch up and the foreign minister also called the collarbone and eklemleştiklerinden clavicularis incisura.
Lower-end, the end of the bone is the thinnest part of the overhang hançersi fprocessus ensiformis) is called. combined with the middle line shows the two side tracks.
Ossification, cartilage is the first draft of the bone connecting the two side parts with each other shows the mid-line.
After five and sixth month of intrauterine life and sternebranın manubrium points are displayed for each of the separate ossification. Bone handle, one for the first sternebra and hançersi overhang, located in the middle line of ossification points in the other 2, 3, 4 th sternebralar point to have two ossification. As mentioned above, the merger between manubriumla ihtiyarlıkta sternebra is the first case, the other adult age groups sternebraların merger is completed.
The skeleton, the chest in front of the cage-shaped part of the vertebrae.
There are three sections in this piece, also called chest:

Breast bone, sternum is

Sides of the front face above the surface rough-kleido sterno - mastoid muscle m below pectoralis major sticks.
Rear face, this face is concave pürtüksüzdür, transverse crest on the more uncertain.
The side edges, each notch on the edge of seven ribs (incisura Costales) shows that they do joint with seven rib cartilage.
There are six notches in the ribs from among them, getting contracts in the latter from the top down.
Upper-end, the base of the bone in the middle of these extremes, the two sides are three notches. Incisura jugularis Konkavlığı upturned middle notch; konkavlığı side notch up and the foreign minister also called the collarbone and eklemleştiklerinden clavicularis incisura.

Ossification, cartilage is the first draft of the bone connecting the two side parts with each other shows the mid-line.
After five and sixth month of intrauterine life and sternebranın manubrium points are displayed for each of the separate ossification. Bone handle, one for the first sternebra and hançersi overhang, located in the middle line of ossification points in the other 2, 3, 4 th sternebralar point to have two ossification. As mentioned above, the merger between manubriumla ihtiyarlıkta sternebra is the first case, the other adult age groups sternebraların merger is completed.
