Why upper limb flexion and lower limb extension in a stroke?
The key to understandis the red nucleus situated in the mesencephalon. These bilateralnucleiinfluence onlythe upper limbs increasing, if working properly, the muscular flexor tone. Strokes sparing the brainstem, and so the red nuclei,will cause upper limb flexion.By contrast, lesionsinvolving the red nucleus or itsprojectionswill cause upper limb extension. The lower limbs are not affected by the red nuclei. They undergo just the control of the cortex, that normally inhibits the extensor tone of the lower limbs. A stroke blocking this control will cause lower limbs extension. Depending on the location, different results are so expected.
Which part of the body does the term brachial refer?
Brachial (as in brachial artery) refers to the upper limbs, the arms.
What is the portion of the body that includes the upper and lower limbs?
appendicular.
Upper motor neuron lesion?
Upper motor neurons: they are the motor cells of cerebral cortex and subcortical centres whose axons constitue the pyramidal and extra-pyramidal tracts(which then descend to end around the motor nuclei of cranial nerves in brainstem and anterior horn cells of the spinal cord)Lower motor neurons: they are the cells of motor nuclei of cranial nerves and anterior horn cells of spinal cords, and their axons which constitute the motor fibres of the peripheral nerves that terminate in the motor end plate of striated muscles.
The cervical enlargement contains nerves that supply the?
Upper Limbs
What is the spinal cord feature associated with the leash of nerves supplying the upper limbs?
The brachial plexus is the spinal cord feature associated with the leash of nerves supplying the upper limbs.
What organs are affected by leprosy?
Skin, nerves, Limbs, Eyes, mucosa of Upper respiratory tract.

The bulge in the spinal cord that gives off nerves to the upper limbs is called?
Lumbar enlargement.
Why are biceps and triceps useful in football?
You can not run without moving your upper limbs in contra lateral positions to lower limbs. (Try to run with upper limbs tied to your body.) Importance of running in football needs no comment. Also imagine the goalkeeper not using his upper limbs!
What are upper limbs?
radial and brachial
Why are the bones of the lower limbs larger and heavier than upper limbs?
Because they have evolved (or were designed, whichever you choose to believe) as to be the primary weight bearing limbs, so they have to be more sturdy to do that job than the upper limbs.
What is the significance of the spinal cord enlargement?
There are two the cervical and the lumbar. They are enlarged because the cervical gives rise to nerves in the upper limbs and lumbar in the lower limbs thus they have more nerves running to and from which accounts for the enlargements.
List the name of the long bones of the upper and lower limbs?
your arms are the upper limbs and your legs are the lower limbs :)
How is the tricep used in sprints?
Without using your upper limbs, you can not run. You can use upper limbs without using your triceps. The world record of 100 meters is little less than 9 seconds. Without using upper limbs, that record will go up to 15 seconds, probably.
What is the brachial plexus group?
This group of nerves innervates the muscles and skin of the entire upper limbs except the Trapezius muscle and the skin near the axilla (arm pit). The plexus comes off the spinal cord at C4,C5,C6,C7,C8 and T1 where they mix and form a plexus. There are 5 main nerves that are formed: Musculocutaneous, axillary, radial, median and ulnar nerves.
