shoulder adduction, elbow flexion and scapular downward rotation
An exercise like a bicep curl would be an example of a single joint movement. You can also move your thumb by the gliding joint that attaches it to the hand. I'm sure there are many others.
Symphysis menti is a primary cartilaginous joint because it is made up of fibrocartilage connecting the two bony components (mandibular symphysis) of the jaw bone. This type of joint provides stability and support to the jaw during movements like chewing and speaking.
The cerebrum makes up 85% of the brain's weight, and it's easy to see why. The cerebrum is the thinking part of the brain and it controls your voluntary muscles
gliding movements
The principal movements occurring at this joint are flexion and extension of the leg, but some rotation also occurs in the flexed position.Flexion and extension of the knee joint are very free movements.
The elbow joint has a humeroulnar and humeroradial joint. The humeroulnar joint allows flexion and extension movements, while the humeroradial joint allows for pronation and supination movements.
pivot joint
The humerus-ulna joint at the elbow is a hinge joint. This type of joint allows for flexion and extension movements, enabling the forearm to bend and straighten relative to the upper arm. The structure of the joint provides stability and allows for a wide range of motion in these two primary directions.
its a joint that flexes
Synergists for the lat pulldown primarily include the biceps brachii, teres major, and the rhomboids. These muscles assist the latissimus dorsi in pulling the weight down, contributing to the overall movement. Additionally, the rear deltoids and the infraspinatus can also help stabilize the shoulder joint during the exercise. Together, these muscles enhance the effectiveness of the lat pulldown by providing support and stability.
Gliding Movements
In addition to simple flexion (bending) and extension (straightening) movements, the knee joint is designed to allow for rotation, gliding, and rolling movements.
