reflexes are fast
Skeletal muscles, which are effectors, are involved in somatic reflexes. Somatic reflexes involve voluntary control of skeletal muscles and are part of the somatic nervous system. Autonomic reflexes, on the other hand, involve the control of smooth muscle, cardiac muscle, and glands, and are part of the autonomic nervous system.
they crazy.
Pretectal nuclei are a group of interconnected cell clusters in the midbrain that play a role in various visual and pupillary reflexes. They receive input from the retina and project to other brain regions involved in controlling eye movements and pupil size. Dysfunction of the pretectal nuclei can lead to abnormalities in these reflexes.
Skeletal muscles are different from other cells in that they have multiple nuclei
Other primitive reflexes in newborns include the moro (startle) reflex, sucking reflex, rooting reflex, and Babinski reflex. These reflexes are integral for survival and neurological development in a newborn baby.
The Human Reflex Physiology Review Sheet states that "Conversely, other reflexes require the involvement of the brain, since many different inputs must be evaluated before the appropriate reflex is determined. Superficial cord reflexes and pupillary responses to light are in this category" (p. 342).

The voluntary muscles - those used for walking moving and speaking. As opposed to involuntary muscles such as those in your intestine or heart.
Two types of body movements in dancing are isolations, where different body parts move independently of each other, and locomotor movements, which involve traveling through space.
The main symptom of upper motor neuron syndrome is spasticity, which is characterized by increased muscle tone and exaggerated reflexes. Other common symptoms include muscle weakness, difficulty with fine motor skills, and impaired voluntary movement.

Moving one hand vertically and the other horizontally simultaneously is challenging due to the brain's motor coordination and the way it processes movements. Each hand is typically controlled by opposite sides of the brain, and coordinating two different movements requires complex neural pathways. This difficulty can also stem from muscle memory and the brain's preference for synchronized, symmetrical movements. With practice, some people can develop the ability to perform this task more easily.
