What part of the nervous system controls reflexes?
The central nervous system CNS is responsible for integrating sensory information and responding accordingly.
It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body.
It also controls simple musculoskeletal reflexes without input from the brain..
What part of the brain is responsible for balance?
cerebellumThe cerebellum, in the back of the brain, controls balance, coordination and fine muscle control (e.g., walking). It also functions to maintain posture and equilibrium.
What part of the brain is responsible for smell?
temporal lobeThe olfactory cortex is vital for the processing and perception of odor. It is located in the temporal lobe of the brain, which is involved in organizing sensory input. The olfactory cortex is also a component of the limbic system.
What are reflexes controlled by?
A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron. As a result, one of your muscles or glands is stimulated.
What part of the brain controls breathing and reflexes?
MedullaMedulla – The primary role of the medulla is regulating our involuntary life sustaining functions such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.
What are 3 reflexes in humans?
Spinal Reflexes. Spinal reflexes include the stretch reflex, the Golgi tendon reflex, the crossed extensor reflex, and the withdrawal reflex.
What causes poor balance in seniors?
Common causes include arthritis and orthostatic hypotension; however, most gait and balance disorders involve multiple contributing factors. Most changes in gait are related to underlying medical conditions and should not be considered an inevitable consequence of aging.
What part of the brain controls reaction time?
The brain stem, which consists of the medulla (an enlarged portion of the upper spinal cord), pons and midbrain (lower animals have only a medulla). The brain stem controls the reflexes and automatic functions (heart rate, blood pressure), limb movements and visceral functions (digestion, urination).
Which side of the brain controls memory?
Temporal LobeTemporal Lobe: side of head above ears situated immediately behind and below the frontal lobes; the temporal lobe controls memory, speech and comprehension. Brain Stem: lower part of brain, leads to spinal cord; the brain stem contains nerve fibers that carry signals to and from all parts of the body.
What part of the brain controls short term memory?
prefrontal cortexImplicit memories, such as motor memories, rely on the basal ganglia and cerebellum. Short-term working memory relies most heavily on the prefrontal cortex.
Is it possible for humans to override reflex actions?
Reflexes need to be fast in order to protect the body. If you pick up a hot plate, the reflex action will make you drop it almost immediately. … However, we can consciously override reflexes. If the hot plate had your dinner on it, you might try to resist the reflex to drop it so that you can put it down safely.
What part of the nervous system controls your internal organs?
autonomic nervous systemThe autonomic nervous system controls our internal organs and glands and is generally considered to be outside the realm of voluntary control. It can be further subdivided into the sympathetic and parasympathetic divisions (Figure 2).
What does each side of the brain control?
Right brain – left brain Each hemisphere controls the opposite side of the body. … In general, the left hemisphere controls speech, comprehension, arithmetic, and writing. The right hemisphere controls creativity, spatial ability, artistic, and musical skills.
Why do I feel off balance when I walk?
Loss of balance or unsteadiness Losing your balance while walking, or feeling imbalanced, can result from: Vestibular problems. Abnormalities in your inner ear can cause a sensation of a floating or heavy head and unsteadiness in the dark. Nerve damage to your legs (peripheral neuropathy).
