Key Concepts

Fibrous Joints

Fibrous joints are joints in which the bones are connected by dense bands of fibrous connective tissue. They typically lack a joint cavity and are often immovable or allow only minimal movement. Examples include sutures found in the skull and syndesmoses where bones are joined by ligaments.

Cartilaginous Joints

Cartilaginous joints are joints where the bones are connected by cartilage. They do not have a synovial cavity and are usually classified based on the type of cartilage present. This category includes both synchondroses, which generally are immovable joints joined by hyaline cartilage, and symphyses, which allow some limited movement via fibrocartilage discs.

Joint Functional Classification (Synarthrosis, Amphiarthrosis, Diarthrosis)

Joints can also be classified functionally by their degree of mobility. Synarthroses are immovable joints, commonly found in fibrous joints like cranial sutures. Amphiarthroses are slightly movable joints, often seen in certain cartilaginous joints such as symphyses. Diarthroses are freely movable joints, which are typically synovial joints characterized by the presence of a distinct joint cavity.

Transcript

00:01 We are asked to classify each of these descriptions with its joint type.

00:09 So first, let's review the types of joints.

00:16 We have fibrous joints.

00:20 Fibrous joints are connected by dense, tough connective tissue that is rich in collagen fibers.

00:43 And fibrous joints are also fixed and can't be moved.

00:47 They are interlocked with irregular edges.

01:05 So some types of fibrous joints include sutures, which are the types of joint that are found in the skull.

01:25 And other fibrous joints are syndesmosis, and they are found between long bones of the body, such as the radio owner and tibiofibular joints.

01:47 And these are movable fibrous joints, and are called amphitheordial.

02:01 They have less range of movement than synovial joints, but typically they're still pretty fixed and can't move very much.

02:14 And lastly, the last type of movement, fibrous joints are called gomphosis.

02:23 And this is a type of joint that's found at the articulation between the teeth and the sockets of the maxilla or mandible.

02:35 And it connects the tooth and the socket.

02:38 And it's called the peridontal ligament.

02:44 The tissue, the fibrous tissue that connects the tooth and suck is called the periodontal ligament.

02:56 The next type we, the next type of joint we have is the cartilaginous joint.

03:02 And they're connected by fibro cartilage or hylin cartilage.

03:24 They allow more movement than fibrous joints, but less than synovial joints.

03:43 And carolatinous joints are subdivided into prerontalus joints.

03:51 Primary or synchondosis and secondary or synthesis cartilaginous joints.

04:12 The epiphyseal or the growth plates are examples of synchondosis.

04:21 Sympathesis are found between the maneuverium and sternum, and also in the intervertebral discs and the pubic synthesis.

04:41 Synovial joints are the most common and most movable joint type in the body.

05:02 And these joints are also called diarthrosis, and they have a synobial cavity.

05:20 Their bones are connected by dense irregular connective tissue that forms an articular capsule surrounding the bones articulating surfaces.

05:30 So now let's take a look at our descriptions here.

05:42 So our first one says exhibits a joint activity...
