What part of the brain is injured when you can't feel anything in your lower body?
When you can't feel anything in your lower body, it may indicate injury to the spinal cord, particularly in the regions that transmit sensory information from the lower body to the brain. Damage to the spinal cord, especially in the thoracic or lumbar regions, can disrupt nerve pathways responsible for sensation. Additionally, injury to the somatosensory cortex in the brain, which processes sensory information, could also contribute to this loss of feeling.
What process by which unchanging information from the senses of taste touch smell and vision is ignored by the sensory receptor cells themselves is called?
The process by which unchanging information from the senses of taste, touch, smell, and vision is ignored by the sensory receptor cells is called sensory adaptation. This phenomenon allows sensory receptors to become less responsive to constant stimuli over time, helping the brain focus on new or changing information that may be more relevant for survival. As a result, individuals can better detect important changes in their environment while filtering out redundant sensory input.
What is the order of a nerve path way?
The order of a nerve pathway typically follows this sequence: sensory receptors detect a stimulus and send signals to sensory neurons, which transmit the information to the spinal cord or brain. From there, interneurons process the information and may relay it to motor neurons, which then carry signals to effectors such as muscles or glands to elicit a response. This sequence allows for the integration of sensory input and the coordination of appropriate motor output.
Why can't a person smell or taste after a brain injury and if they do they just smell and taste smoke or have a taste like metal?
Loss of smell and taste after a brain injury can occur due to damage to the olfactory nerves or brain regions responsible for processing sensory information. When a person experiences phantom smells of smoke or tastes of metal, it may be due to misfiring neurons in the brain sending incorrect signals. This can lead to distortions in how the brain interprets sensory information, creating the perception of certain smells or tastes.
How does sensory system affects behavior?
The sensory system plays a key role in influencing behavior as it processes external stimuli and relays information to the brain. Sensory input can impact emotions, decision-making, and responses to the environment. For example, a loud noise may trigger a fight-or-flight response, while a pleasant smell can induce feelings of relaxation or comfort.
What is a sensory neurones?
A sensory neuron is one that brings information about environmental simuli to the brain. It may also be called an afferent neuron.
What does your brain think you look like?
Your brain creates a mental image of what you look like based on sensory information and memories. This image may not always match your actual appearance, as it can be influenced by emotions and past experiences.
What is perceptious?
It seems like there may be a typo. Perhaps you mean "perception," which refers to the way our brain organizes and interprets sensory information from our environment. It influences how we understand and make sense of the world around us.
What is the primary function of nervous tissue?
To relay sensory information to the brain for interpretation and motor information to the muscles for voluntary or involuntary control. Nervous tissue also fulfills many other roles, like innervating organs that may release hormones.

What is the parential lobe?
There is no brain structure called the "parential lobe." It is possible that you may be referring to the parietal lobe, which is a region of the brain involved in processing sensory information, spatial reasoning, and some aspects of language. If you meant something else, please provide more context for clarification.
What happens when dorsal root is damaged?
Damage to the dorsal root can cause sensory deficits, such as numbness, tingling, or loss of sensation in the corresponding dermatome. This may affect the transmission of sensory information from the peripheral nerves to the spinal cord and brain. Additionally, reflexes may be impaired as a result of the disruption in the sensory input to the spinal cord.
What do you think that the up and down arrows you carved into spinal cord are meant to represent?
The up and down arrows carved into the spinal cord likely symbolize the flow of information and signals between the brain and the body, illustrating the central role of the spinal cord in communication within the nervous system. The upward arrow may represent sensory information traveling to the brain, while the downward arrow could signify motor commands being sent from the brain to the body. Together, they highlight the dynamic interplay of sensory and motor functions essential for movement and perception.
What is a disorder in which the signals from the various sensory Organs are processed in the wrong cortical areas?
The disorder in which signals from various sensory organs are processed in the wrong cortical areas is known as cross-modal perception or sensory processing disorder. In these conditions, the brain may misinterpret sensory information, leading to confusion or heightened sensitivity to stimuli. This can result in individuals experiencing sensations inappropriately, such as "seeing" sounds or "hearing" colors, impacting their ability to interact with the environment effectively.
How the brain responds or may not respond to a stimulus.?
The brain responds to a stimulus through a complex process involving sensory neurons that transmit information to specific brain regions, where it is interpreted and processed. Depending on the nature and significance of the stimulus, the brain can exhibit various responses, such as reflex actions or conscious decision-making. In some cases, the brain may not respond if the stimulus is deemed irrelevant or if it is habituated to repeated exposure. Additionally, factors like attention, emotional state, and context can influence the brain's responsiveness to stimuli.
Which part of the brain has been damaged when there is no sensation in the body?
Damage to the somatosensory cortex, located in the parietal lobe of the brain, may result in a lack of sensation in the body. This area is responsible for processing tactile information and interpreting sensory input from different parts of the body.
