How do extrinsic eye muscles differ in action from the instrintic eye muscles?
Extrinsic eye muscles move the eyeball in relation to the rest of the body, whereas intrinsic muscles move structures within the eyeball.A: The extrinsic muscles control the movement of the eyes.The extrinsic muscles are controlled by the somatic nervous system(voluntary) The intrinsicmuscles control the lens and pupil. The intrinsiceye muscles, (including the iris sphincter, radial pupilodilator muscles and the ciliarymuscle), are under the control of the autonomic nervous system(involuntary)
What extrinsic eye muscles are controlled during the convergence reflex?
The medial rectus muscles are primarily responsible for the convergence reflex. When focusing on a near object, these muscles contract to rotate both eyes inward, allowing them to converge and maintain single binocular vision.
How many muscles does it take to stick your tong out?
Sticking out your tongue primarily involves the use of about 8 muscles. These include intrinsic muscles, which change the shape of the tongue, and extrinsic muscles, which control its position. The main extrinsic muscles involved are the genioglossus, hyoglossus, and styloglossus. Together, they allow for the movement and extension of the tongue.
The extrinsic muscles of the hand originate where?
The extrensic muscles of the hand originate from the lateral epicondyle of the humerous
What do geniohyiod hyoglossus and stylohyoid have in common?
They are all extrinsic muscles of the tongue, used for crude movement.
Function of the extrinsic muscles of the eye?
The extrinsic muscles of the eye control the movement of the eyeball and enable eye movements, such as looking up, down, and sideways. These muscles work together to coordinate eye movements and allow us to track objects and focus on different points in our visual field.
What do the muscles genioglossus and hyoglossus and styloglossus have in common?
They are all extrinsic muscles of the tongue, used for crude movement.
What you control the movement of these muscles?
voluntary muscles
What do you control the movement of these muscles?
voluntary muscles
Muscles that you connot control movement of are muscles?
Involuntary muscles
The extrinsic muscle of the hand originate on the what?
Extrinsic muscles of the hand originate in the antebrachium (forearm).
You control the movement of these muscles?
something.
