What is the function of the brachialis?
Thie brachialis is a muscle in the arm of the upper limb and it is the primary flexor of the elbow joint.
What is a flexor reflex?
Flexor reflex occurs when powerful stimuli (most often pain) causes the whole limb to be withdrawn from the site of stimuli. Reciprocal inhibition is vital (this relaxes the antagonist muscles) allowing the joint to be flexed and hence remove itself from the painful stimulus.
What does place where two bones meet?
Two bones come together at a joint or articulation. There are many different types of joints such as the "hinge" joint, the "ball and socket" joint, the "ellipsoid" joint, and more. Prominent joints on the human body include elbows and knees.
Is bending the elbow an example of flexion?
yes because it allows the arm to move back and forth, like a door hingeThe elbow is a hinge joint.The elbow joint is a hinge joint.
What holds the pubic joint together?
The left and right pubic bones meet at the pubic symphysis (English) or symphisis pubis (Latin).The joint that is formed by the hip bone (Os Coxa) and the sacrum is the sacroiliac joint.
What does the 'extensor muscle' do?
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
What is the difference between flexor and extensor?
Extensor muscles help to straighten or extend the joint while flexors do the opposite, bending it.
Is tricepes flexor?
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
Do skeletal muscles work in paires?
All skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Do most skeletal muscles work in antagonistic pairs?
Yes. Skeletal muscles will have a flexor and an extensor. The flexor bends the joint. The extensor straightens it out again.
Is the knuckle a immovable joint?

What are extensors?
Extensor muscles open a joint and are the opposite to flexor muscles, which close it. I imagine triceps are extensor, while biceps are flexor.
How does a chicken move its wings?
The flexor bends the joint, and since the flexor cannot lengthen by itself to push the bone back to straighten the joint, the extensor pulls the bone in the opposite direction. Tendons attach muscles to bones and helps the chicken move its wing.
Do the triceps flex or extend the forearm?
extensorThe triceps brachii is an extensor. It is the large muscle on the back of the arm and is primarily the muscle used for extension of the elbow joint or straightening of the arm. The triceps is also an antagonist of the biceps and the brachialis muscles.ExtensorsTriceps is not a flexor. It is extensor of the elbow joint.
Does a flexor muscle open a joint?
No the flexor closes the joint.
What type of movement does the contraction of a flexor muscle?
Any flexor muscle decreases the angle of a joint. When you flex your biceps brachii, the distance between your forearm and arm becomes closer together. When you use your extensors on the same joint, your arm will straighten.
What is brachioradialis?
this muscle is one among the 7 superficial extensor muscles of the postertor compartment of the forearm. this is otherwise known as the supinator longus. functionally it is a flexor of the elbow but it is grouped under extensor muscles. this muscle forms a fleshy bulk along the lateral border of the forearm. it forms the latersl boundary of cubital fossa. supplied by radial nerve. it acts as the flexor of the elbow joint.
