In the shoulder joint, the spherical head of the humerus (upper arm bone) fits into the glenoid cavity of the scapula (shoulder blade). Ball-and-socket joints are classified functionally as multiaxial joints because they can move bones along several axes.
Also, which type of joint is multiaxial movement?
resemble condyloid joints, but they allow greater freedom of movement. Each articular surface has both concave and convex areas. the spherical or hemispherical head of one bone articulates with the cuplike socket of another. These joints are multiaxial and the most freely moviing synovial joints.
Is a Plane joint multiaxial?
Plane joints: These joints permit gliding and sliding movements owing to the fact that the articular surfaces of the bones are flat meaning they only allow movement to occur in a single plane (uniaxial joints). Condyloid joints: These joints are biaxial.
What does multiaxial joint mean?
multiaxial joint. (mŭl′tē-ăk′sē-?l, -tī-) n. A joint in which movement occurs in a number of axes. polyaxial joint.
What is an example of a ball and socket joint?
Examples of this form of articulation are found in the hip, where the rounded head of the femur (ball) rests in the cup-like acetabulum (socket) of the pelvis, and in the glenohumeral joint of the shoulder, where the rounded head of the humerus (ball) rests in the cup-like glenoid fossa (socket) of the shoulder blade.
Why is it called a ball and socket joint?
medical Definition of ball-and-socket joint. : an articulation (as the hip joint) in which the rounded head of one bone fits into a cuplike cavity of the other and admits movement in any direction — called also enarthrosis.
What are some examples of hinge joints?
Hinge Joints in the Body. Following are some examples of hinge joints throughout the body. The elbow joint is a joint in the human body. Thus, it is called the humeroulna joint in the medical community. The humeroulnar joint is placed in between the trochlear notch of ulna and the trochlea of the humerus.
What does biaxial joint mean?
biaxial joint. (bī-ăk′sē-?l) n. A joint in which there are two principal axes of movement situated at right angles to each other.

What is a Condyloid joint?
A condyloid joint (also called condylar, ellipsoidal, or bicondylar) is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction.
What type of joint is the toe?
Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. The simplest hinge joints in the body are the interphalangeal joints found between the phalanges of the fingers and toes.
What type of joint is in the wrist?

Is the elbow a hinge joint?
The elbow joint is the synovial hinge joint between the humerus in the upper arm and the radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the body. The elbow is specific to humans and other primates.
How are the hip and shoulder joints similar?
The hip and the shoulder are both ball and socket joints that have cartilage, ligaments, labrum, and a surrounding capsule. There are some differences between these joints that influence the treatment for injuries and painful conditions. The hip is much more constrained or inherently stable than the shoulder.
Is the knee is a ball and socket joint?
Hinge joints, such as the elbow and knee, limit movement in only one direction so that the angle between bones can increase or decrease at the joint. The shoulder and hip joints form the only ball and socket joints in the body.
Is the knee a biaxial joint?
This joint is the largest joint in the body and is formed by the articulation of the femur bone in the thigh with the tibia in the lower leg. The knee falls under the uniaxial as it is a hinge joint and it moves in one plane with slight rotational movement, but the rotation is not enough to be considered significant.
What are joints that do not allow movement known as?
Cartilaginous joints contain cartilage and allow very little movement; there are two types of cartilaginous joints: synchondroses and symphyses. Synovial joints are the only joints that have a space (a synovial cavity filled with fluid) between the adjoining bones.
What type of joint is the intervertebral joint?
(2) A symphysis consists of a compressable fibrocartilaginous pad that connects two bones. 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.
Is a Plane joint multiaxial?
Plane joints: These joints permit gliding and sliding movements owing to the fact that the articular surfaces of the bones are flat meaning they only allow movement to occur in a single plane (uniaxial joints). Condyloid joints: These joints are biaxial.
How many planes can biaxial joints move?
Some joints allow movement in only one plane; these joints are uniaxial. One common uniaxial joint is the hinge joint. Your elbow is one example; can you think of others? Biaxial joints allow movements in two planes.
What is the definition of a fixed joint?
Fixed joints. Some of your joints, like those in your skull, are fixed and don’t allow any movement. The bones in your skull are held together with fibrous connective tissue. Slightly movable joints.
Is a saddle joint multiaxial?
The movements are as same as in the condyloid joint; that is to say, flexion, extension, adduction, abduction, and circumduction are allowed; but no axial rotation. Saddle joints are said to be biaxial, allowing movement in the sagittal and frontal planes.
What type of joint is the knuckle?
Proximal Knuckles. The knuckles of the hand or metacarpal-phalangeal joints (MCP) are condyloid joints that allow flexion and extension as well as limited lateral deviation.
