The point at which two or more bones meet is called a joint , or articulation. Joints are responsible for movement, such as the movement of limbs, and stability, such as the stability found in the bones of the skull. There are two ways to classify joints: on the basis of their structure or on the basis of their function. The structural classification divides joints into bony, fibrous, cartilaginous, and synovial joints depending on the material composing the joint and the presence or absence of a cavity in the joint.

The Long and the Short of It: The Five Types of Bones

Joints hold the skeleton together and support movement. There are two ways to categorize joints. The first is by joint function, also referred to as range of motion. The second way to categorize joints is by the material that holds the bones of the joints together; that is an organization of joints by structure. Joints in the human skeleton can be grouped by function range of motion and by structure material.

Here are some joints and their categorizations. Immovable joints called synarthroses include skull sutures, the articulations between the teeth and the mandible, and the joint found between the first pair of ribs and the sternum. Examples of joints allowing slight movement called amphiarthroses include the distal joint between the tibia and the fibula and the pubic symphisis of the pelvic girdle.

Joints allowing full movement called diarthroses include many bone articulations in the upper and lower limbs. Examples of these include the elbow, shoulder, and ankle. Fibrous Joints. Between the articulations of fibrous joints is thick connective tissue, which is why most but not all fibrous joints are immovable synarthroses. There are three types of fibrous joints:.

These joints have serrated edges that lock together with fibers of connective tissue. The distal joint between the tibia and fibula is an example of a syndesmosis.

Cartiliginous Joints. Joints that unite bones with cartilage are called cartilaginous joints. There are two types of cartilaginous joints: 1 A synchrondosis is an immovable cartilaginous joint. One example is the joint between the first pair of ribs and the sternum. This type of joint allows for some movement. The hip bones, connected by the pubic symphysis, and the vertebrae, connected by intervertebral discs, are two examples of symphyses. Synovial Joints. Synovial joints are characterized by the presence of an articular capsule between the two joined bones.

Bone surfaces at synovial joints are protected by a coating of articular cartilage. Synovial joints are often supported and reinforced by surrounding ligaments, which limit movement to prevent injury. There are six types of synovial joints:. Major gliding joints include the intervertebral joints and the bones of the wrists and ankles.

These joints allow for flexion and extension. Major hinge joints include the elbow and finger joints. At the top of the spine, the atlas and axis form a pivot joint that allows for rotation of the head. The wrist joint between the radius and the carpal bones is an example of a condyloid joint.

The hip and shoulder joints are examples of ball and socket joints. Human Anatomy Atlas offers thousands of models to help understand and communicate how the human body looks and works. Information on joint replacement from the American Academy of Orthopaedic Surgeons.

Joints Can Be Grouped By Their Function into Three Ranges of Motion Immovable joints called synarthroses include skull sutures, the articulations between the teeth and the mandible, and the joint found between the first pair of ribs and the sternum.

Type of Joint Function Examples Synarthrosis range of joint motion: no movement Skull Sutures, articulations of bony sockets and teeth in facial skeleton Amphiarthrosis range of joint motion: little Movement distal joint between the tibia and the fibula and the pubic symphysis Diarthrosis range of joint motion full movement Elbow, shoulder, ankle 2.

There are three types of fibrous joints: 1 Sutures are nonmoving joints that connect bones of the skull. There are six types of synovial joints: 1 Gliding joints move against each other on a single plane.

Bones Come Together: Types of Joints in the Human Body

Click Image to Enlarge. Joints are the areas where 2 or more bones meet. Most joints are mobile, allowing the bones to move. Joints consist of the following:. This is a type of tissue that covers the surface of a bone at a joint.

Is this person double jointed? No; there is no such thing, at least as far as humans are concerned. However, some people, like the individual pictured here, are much more flexible than others, generally because they have looser ligaments. Physicians call the condition joint hypermobility. Joints are locations at which bones of the skeleton connect with one another. A joint is also called an articulation.

Anatomy of a Joint

Joints can be classified by the type of the tissue present fibrous, cartilaginous or synovial , or by the degree of movement permitted synarthrosis, amphiarthrosis or diarthrosis. In this article, we shall look at the classification of joints in the human body. A fibrous joint is where the bones are bound by a tough, fibrous tissue. These are typically joints that require strength and stability over range of movement.

Joints, responsible for movement and stability of the skeleton, can be classified based on structure or function. The point at which two or more bones meet is called a joint or articulation. Joints are responsible for movement e. There are two ways to classify joints: on the basis of their structure or on the basis of their function. The structural classification divides joints into fibrous, cartilaginous, and synovial joints depending on the material composing the joint and the presence or absence of a cavity in the joint.

The human skeleton has a number of functions, such as protection and supporting weight. Different types of bones have differing shapes related to their particular function. There are flat bones in the skull occipital, parietal, frontal, nasal, lacrimal, and vomer , the thoracic cage sternum and ribs , and the pelvis ilium, ischium, and pubis. The function of flat bones is to protect internal organs such as the brain, heart, and pelvic organs. Flat bones are somewhat flattened, and can provide protection, like a shield; flat bones can also provide large areas of attachment for muscles.

Classification of Joints

The question of how many joints there are in the human body is a difficult one to answer because it depends on a number of variables. This includes:. The estimated number is between and The adult human skeletal system has a complex architecture that includes named bones connected by cartilage, tendons, ligaments, and three types of joints:. Although the actual number of joints in any one person depends on a number of variables, the estimated number is between and Cartilage cushions joints and helps them work smoothly.

Ради всего святого, зачем вы это сделали. Чтобы скрыть свою маленькую тайну. Стратмор сохранял спокойствие. - И что же это за секрет.

Он сидел у нее на животе, раскинув ноги в стороны. Его копчик больно вдавливался в низ ее живота через тонкую ткань юбки. Кровь из ноздрей капала прямо на нее, и она вся была перепачкана. Она чувствовала, как к ее горлу подступает тошнота. Его руки двигались по ее груди.

Возле фреоновых помп. Сьюзан повернулась и направилась к двери, но на полпути оглянулась. - Коммандер, - сказала.  - Это еще не конец. Мы еще не проиграли.

Полнейшее безумие. - Это невозможно! - воскликнула она.  - Вы проверили сигналы ошибки. Быть может, в ТРАНСТЕКСТЕ какой-нибудь сбой и… - Все в полном порядке. - Но это значит, что пароль неимоверной длины.

И проклинала. Как я могла не выключить монитор. Сьюзан понимала: как только Хейл заподозрит, что она искала что-то в его компьютере, то сразу же поймет, что подлинное лицо Северной Дакоты раскрыто. И пойдет на все, лишь бы эта информация не вышла из стен Третьего узла.

Коммандер спускался по лестнице, ни на мгновение не сводя с него глаз. Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна. - Вы что-то сказали.

Я скажу вам, кто его сегодня сопровождает, и мы сможем прислать ее к вам завтра. - Клаус Шмидт, - выпалил Беккер имя из старого учебника немецкого. Долгая пауза.

Это был молодой человек. В верхней губе у него торчала серебряная запонка, на нем была черная кожаная куртка, надетая на голое тело. - Какого черта тебе надо? - прорычал он хриплым голосом - с явным нью-йоркским акцентом.

Сьюзан смутилась. - Хорошо, а что, если… кошка. - Жила! - не задумываясь выпалил Беккер.

И увидел, что никто даже не улыбнулся, когда текст был наконец расшифрован.

Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике. Чуть впереди, у остановки, притормозил городской автобус. Беккер поднял. Дверцы автобуса открылись, но из него никто не вышел.

 Королева информации! - приветствовал ее толстяк. Он всегда питал слабость к Мидж Милкен. Умница, да к тому же единственная женщина, не упускавшая случая с ним пококетничать.  - Как твои дела. - Не жалуюсь.

 Первичное! - воскликнула. И повернулась к Джаббе.  - Ключ - это первичное, то есть простое число.

 - Энсей Танкадо и есть Северная Дакота.
