A reflex that does not pass through the brain is termed as?
Kekegotanswers
Simple, unconditioned or natural reflexes do not involve the brain. These reflexes occur when a receptor that goes to the spinal cord is stimulated by an impulse or effector. The effector neuron sends a response to the muscle or the gland thus causing an instant action. An example of this type of action would be when you blink your eye due to strong light.

Reflexes are not carried to the brain?
A reflex arc does not pass through the brain. The somatic reflex arc and autonomic reflex arc are two types.
Pass through the cochlea and are transformed into nerve impulses and sent to the brain?
sound waves
Describe the reflex arc?
A reflex arc is the neural pathway that mediates a reflex action. In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This characteristic allows reflex actions to occur relatively quickly by activating spinal motor neurons without the delay of routing signals through the brain, although the brain will receive sensory input while the reflex action occurs.
Why is the retina the first membrane of the eye?
because it has millions of nervous cells that line its interior that transform the stimuli into info captured by the brain, brought by the optic nerve. without the retina being the first layer, the info, would not make it to the brain ('cause it wouldn't pass through the other layers)
How does the body defend itself from meningitis?
Through the brain has very good blood supply, there is something called as blood brain barrier. There are tight junctions in the cappilaries and from outside a layer of connective tissue cells. So that bacteria cannot pass through this barrier. So meningitis is relatively rare disease.

Why is the patellar reflex called a somatic reflex?
The Patellar reflex is an example of a somatic reflex. This refers to the branch of the nervous system that the reflex pertains to. The somatic branch is part of the Peripheral Nervous system, meaning that it's reflex arc does not pass through the central nervous system (the spinal cord and the brain)
Why does reflex reinforcement work?
Instead of being processed in the brain, a reflex arc is processed in the vertebra, this allows for faster reflexes. Example of when the reflex arc is used is when a person touches a hot stove. The immediate response (which the reflex arc causes) is to pull away, but it doesn't really hurt till a few seconds after. This is because the brain was first bypassed, but has now had time to process what happened.
What part of the central nervous system controls reflexes?
The spinal cord controls reflexes. When a sensory stimulus is detected, the signal is sent to the spinal cord, which then produces a reflex action without needing input from the brain. This allows for quick responses to potential threats or dangers.
What is opqque?
Opaque is antonym for transparent. Transparency allows light to pass through. Glass, water are examples. If light is not allowed to pass through then such a substance is termed as opaque.
What veins pass through the transverse vertebral foramina?
No veins pass through the the transverse foraminae. The vertebral arteries, however, pass through these spaces on their way to the brain.
Can nicotine pass through the blood brain barrier?
yes
What part of the part does all neurons pass through?
The brain stem.
What are the only things that can pass through the blood brain barrier?
sledgehammer
How many gallons of blood goes through your brain every day?
360 gallons of blood pass through the brain every 24 hours
How is it possible for the GI tract to have complete reflex arcs without having to pass impulses through the central nervous system?
Ganglion
Most sensory tracts pass through this structure in the brain?
The arterial cortex.
