If the term ends in ex the plural is formed by?
If a term ends in "ex," the plural is typically formed by changing "ex" to "ices." For example, the plural of "cortex" is "cortices," and the plural of "index" is "indices." This rule applies to many scientific and medical terms. However, some exceptions may exist, so it's always good to check specific words.
List the 4 major lobes of the cerebral hemisphere and describe what each is primarily responsible for?
The frontal lobe, primarily asociated with personality and conscious thought. The temporal lobe which has ties with the sense of sound. The occipital lobe which is commonly accepted as the area dealing with site. The parietal lobe is largely unknown but is though to deal with spacial awareness and navigation.************************************************If you need more, here's a bit of a further elaboration.The four major lobes of the cerebral hemisphere are:The frontal lobe: contains most of the dopamine-sensitive neurons in the cerebral cortex. The dopamine system is associated with reward, attention, long-term memory, planning, and drive. The executive functions of the frontal lobes involve the ability to recognize future consequences resulting from current actions, to choose between good and bad actions (or better and best), override and suppress unacceptable social responses, and determine similarities and differences between things or events. Therefore, it is involved in higher mental functions. The frontal lobes also play an important part in retaining longer term memories which are not task-based. These are often memories associated with emotions derived from input from the brain's limbic system. The frontal lobe modifies those emotions to generally fit socially acceptable norms. Psychological tests that measure frontal lobe function include finger tapping, Wisconsin Card Sorting Task, and measures of verbal and figural fluency.The temporal lobe: The temporal lobe is involved in auditory perception and is home to the primary auditory cortex. It is also important for the processing of semantics in both speech and vision. The temporal lobe contains the hippocampus and plays a key role in the formation of long-term memory.The occipital lobe: is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. This is very important; it contains the primary visual cortex.The parietal lobe: is a lobe in the brain. It is positioned above (superior to) the occipital lobe and behind (posterior to) the frontal lobe. The parietal lobe integrates sensory information from different modalities, particularly determining spatial sense and navigation. For example, it comprises somatosensory cortex and the dorsal stream of the visual system. This enables regions of the parietal cortex to map objects perceived visually into body coordinate positions. The parietal lobe plays important roles in integrating sensory information from various parts of the body, knowledge of numbers and their relations, and in the manipulation of objects. Portions of the parietal lobe are involved with visuospatial processing. Although multisensory in nature, the posterior parietal cortex is often referred to by vision scientists as the dorsal stream of vision (as opposed to the ventral stream in the temporal lobe). This dorsal stream has been called both the 'where' stream (as in spatial vision) and the 'how' stream (as in vision for action.P.S. I hope that helped. Thanks. =)
What part of the brain does the thalamus transfer impulses to?
cortex
What is the relay station for nerve impulses?
The relay station for nerve impulses is the thalamus in the brain. It receives sensory information from various parts of the body and relays it to the appropriate areas of the cerebral cortex for processing.
What receives and transmits all sensory impulses except smell?
Thalamus
What part of the brain receives sensory info and relay it to the cerebral cortex?
thalamus
Most nerve impulses from our senses are routed through the?
Most nerve impulses from our senses are routed through the thalamus before being relayed to the appropriate regions in the brain for processing. The thalamus acts as a relay station for sensory information, helping to regulate which signals are sent to the cortex for further analysis.
What conducts impluses from the thalamus to the primary somaticsensory area of the cortex on the same side?
The primary pathway that conducts impulses from the thalamus to the primary somatosensory area of the cortex on the same side is the ventral posterolateral (VPL) nucleus of the thalamus. The VPL receives sensory information from the body and transmits it to the primary somatosensory cortex located in the postcentral gyrus. This pathway is crucial for processing tactile sensations, proprioception, and pain. The information is relayed ipsilaterally, meaning it goes to the same side of the cortex as the side of the body from which the sensory input originated.
What is the major relay station for sensory information ascending to primary sensory areas of the cerebral cortex?
The thalamus is the major relay station for sensory information ascending to the primary sensory areas of the cerebral cortex. It receives sensory input from various parts of the body and relays this information to the appropriate cortical areas for further processing and interpretation.
On the way to the temporal lobe's auditory cortex neural impulses from the auditory nerve are first relayed to the?
Auditory nerves are first relayed to the thalamus on the way to the temporal lobes auditory cortex. The thalamus is the gray matter between the cerebral hemispheres.
What is the relay center for sensory impulses?
The thalamus is the main relay station for all sensory impulses going to the cortex of the brain, except olfactory sensations. Afferent nerve fibers come into the thalamus, which sends the signals on to the correct part of the cerebral cortex for processing. This is a large, oval structure located on either side of the third ventricle of the brain.
What part of the spinal cord receives sensory impulses from the body?
somatosensory cortex
What part of the brain serves as a switching station for sensory input?
The thalamus serves as a switching station for sensory input in the brain. It receives information from various sensory systems and relays it to the appropriate areas of the cerebral cortex for further processing.
Where visual images are perceived?
In the primary visual cortex. Information passes from the retina to the bipolar cells, these impulses travel through the optic nerve, which is made up of the axons of ganglion cells, and extend to several regions of the brain including the thalamus. The impulses are then sent further along neurones, to the primary visual cortex, where further processing of the information occurs.
