Motor impulses? Those occur in engines. If you are talking about the spinal cord then you mean motojoto impulses. They enter through the ventral roots. First theories on motojoto impuses were by Akari Motojoto, a Japanese scientist.

Sensory neurons enter the spinal cord via what root?
ventral root yo
Where do impulses to the muscles originate?
The "impulses" to skeletal muscles come primarily from alpha motor neurons in the ventral horn of the spinal cord. These neurons release acetylcholine on the muscles, which causes sodium to enter the muscle, leading to contraction. The alpha motor neurons themselves get input from several sources, such as the primary motor area in the cerebral cortex of the brain. However, even this brain area gets input from other brain areas, including sensory areas. In a certain sense, the impulses to the muscles "originate" from the environment in the form of sensory signals.
What structure detects the stimulus in the reflex action?
The stimulus is detected by temperature or pain receptors in the skin. These generate impulses in sensory neurons. The impulses enter the CNS ( Central nervous system ) through a part of the spinal nerve called the Dorsal root.
Does a spinal tap enter the ventral cavity?
No
Where do nerve impulses travel from to enter the bundle branches?
Nerve impulses come through the sinus node of the heart to the bundle of His and then move into the right and left bundle branches.
What type of impulses enter and leave from opposite sides of the spinal cord?
Afferent impulses enter the spinal cord from the posterior section. They may get processed by interneurons. And, in most cases they exit the spinal cord through the efferent neurons in the anterior section. The reason that they refer to this as being opposite sides has to do with what are called the 'horns' inside the spinal cord. The afferent impulses enter the dorsal horns in the back and the efferent impulses exit in the front, the anterior horns. This may be why your reference, your teacher, or a book, says that impulses enter and leave from opposite sides of the spinal cord.
If you enter a room and smell a strong odor you have experienced what?
Sensory adaptation
How do sound vibrations carried from the ear to the nerve cells?
Sound waves enter through the outer ear, then sound waves move through the ear canal. Next sound waves strike the eardrum, causing it to vibrate, then vibrations enter the middle ear. Then the hammer picks up the vibrations, then vibrations are passed to the anvil. Next the vibrations are transmitted to the stirrup, then a vibrating membrane transmits vibrations to the inner ear, and then vibrations are channeled into the cochlea. Then nerve cells detect vibrations and convert them to electrical impulses, then electrical impulses are transmitted to the brain. Then the brain interprets electrical impulses as sound.
What is the path of sound vibrations and impulses from pinna to brain?

Which part of your ear do sound waves enter through?
Sound waves technically enter through the Auricle, the outside, visible part of the ear. From there, they hit the Tympanic Membrane (ear drum) and vibrate the ossicles (small bones in the ear), where the waves are transferred into the cochlea and organ of corti, where they're detected and changed to nerve impulses.
How does sperm from one earthworm enter another earthworm for cross-fertilization?
Two worms come together along their ventral sides and become temporarily joined by the secretion of a "slime tube". Sperm is discharged from the seminal vesicles of both Worms's long seminal grooves on the ventral body surfaces, and enter the seminal receptacles of the other worms.
Trace the path of sound waves as they enter the ear Start with the outer ear?
Sound waves first enter the outer ear, which consists of the pinna (visible portion) and the ear canal. The pinna helps collect sound waves and directs them into the ear canal. The sound waves then travel through the ear canal and reach the eardrum (tympanic membrane) at the end of the canal.
