If the condition has an identifiable cause, it is designated as extrinsic.

The stenrocleidomastoid muscle bilaterally does neck extension, while unilaterally, they laterally flex the Neck to the same side of the muscle contracting, and rotates th neck to the contra lateral side. So if you rotate to the left, the right sternocleidomastoid muscle is working. The right stenrocleidomastoid will also cause right lateral flexion( side bending)
Infectious disease may be referred to as extrinsic because the root cause came from outside of the patient's body. In contrast, a genetic condition may be considered intrinsic, because the cause is within the patient.
Many eye problems can cause or trigger different headache types in susceptible individuals. For appropriate diagnosis, please seek the help of a headache specialist,
Abductor muscles are the muscles which cause abduction. prime example being lateral head of the shoulder abducts your arms to the side of your body. similarly you have the muscles in your lower body which abducts your legs to the sides.
The medical term for crows feet is lateral canthal wrinkles, and is defined as "the wrinkles at the lateral or temperal side of the eye."Lateral canthal wrinkles are caused by the contraction of the lateral side of the orbital portion of the obicularis oculi (the obicularis oculi is the muscle that runs the circumference of the eye.) Wrinkles as a result of squinting or smiling referred to as dynamic lateral canthal wrinkles. These wrinkles are the result of in folding and pleating of the overlying skin which radiate away from the lateral canthus (the lateral canthus refers to either of the temporal corners of the eye where the upper and lower eyelids meet).These canthal winkles are perpendicular to the direction of the lateral muscle fibers and of the orbital portion of the obicularis oculi, which run mostly in a vertical direction around the lateral canthus. These type of wrinkles can be diminished through the use and injection of a neurotoxin (trade name Botox). Botox is also used clinically in small quantities to treat strabismus(the abnormal alignment of one or both eyes), facial spasms and other neurological disorders characterized by abnormal muscle contractions. However, in the majority of cases it is caused by environmental factors, e.g. sun damage. If this is the case, then the wrinkles will be apparent, regardless of the person's facial expressions. This type of wrinkle is referred to as a static, lateral canthal wrinkle.When the bulk of lateral canthal wrinkles are static, the wrinkles are commonly called crow's feet but more affectionately called laugh lines. The neurotoxin previously mentioned, (Botox) in this case, is less effective and only through resurfacing, soft tissue filler, or reinforcement at the Lateral Canthus might this help modify static wrinkles of the lateral canthus. Other more invasive procedures are: canthoplasty, tarsal strip resuspension, lateral canthal- plication, canthopexy, lateral retinacular suspension and inferior retinacular suspension.When crows feet are caused by hyperactivity(a condition characterized by restlessness of the lateral portion of the obicularis oculi); injections of Botox can play a significant role in reducing the wrinkles.
Some of the major causes of amblyopia are as follows: Strabismus.Anisometropia.Cataract.Ptosis.Nutrition.Heredity.A misalignment of the eyes (strabismus) is the most common cause of functional amblyopia.
Crossed eyes in cats, also known as strabismus, can be caused by genetics, nerve damage, or eye muscle weakness. Treatment options may include surgery, medication, or corrective lenses, depending on the underlying cause. Consulting a veterinarian is recommended for proper diagnosis and treatment.
