What is a collection of genetically identical cells that are permanently associated but in which little or no integration of cell activities occurs?
A clonal colony is a collection of genetically identical cells that are permanently associated but where little or no integration of cell activities occurs. Each cell within the colony retains its own functions and activities, resulting in a group of cells that are physically connected but function independently.
Protrusion of the brain through a defect in the skull is called a?
Protrusion of the brain through a defect in the skull is called an encephalocele. It is a type of neural tube defect that occurs when the neural tube (which forms the baby's brain and spinal cord) does not close properly during embryonic development. Encephaloceles can lead to neurological issues and require surgical intervention.
The embryonic origin of all neural tissue?
Neural tissue originates from the ectoderm layer of the developing embryo. This layer gives rise to the neural tube, which later differentiates into the central nervous system (brain and spinal cord) and the peripheral nervous system. Neuromesodermal progenitors are involved in the development of both neural and mesodermal tissues during embryonic development.
What is the difference between tonic and phasic responses in the context of neural activity?
Tonic responses are continuous and sustained neural activity, while phasic responses are brief and transient bursts of neural activity.
What is neural coding?
Neural coding is the process by which the nervous system represents and processes information. It involves the conversion of sensory stimuli and other sources of input into patterns of neural activity, which are then interpreted by the brain to generate perception, thoughts, and behaviors. Different types of neural coding mechanisms exist, such as rate coding (based on firing rate of neurons) and temporal coding (based on the timing of neural spikes).
What is Neural integration in the somatosenory system?
The process by which inhibitory and excitatory post-synaptic potentials summate and control the rate of firing of a neuron.
What is osteophytic encroachment of the neural central joints at C56?
Osteophytic encroachment of the neural central joints at C5-6 is when degeneration of a disc causes obstruction. This obstruction occurs at the foramina at C4-5.
The process of integrating information processed simultaneously by multiple neural networks can be detected as a pattern of what?
The process of integrating information processed simultaneously by multiple neural networks can be detected as a pattern of synchronized neural activity. This synchronization allows for the coordination and integration of information across different brain regions, facilitating complex cognitive processes.
What does neural convergence linked to perception in general?
Neural convergence refers to the phenomenon where multiple neurons synapse onto a single neuron, allowing for the integration of information from various sources. In terms of perception, this process enhances the brain's ability to combine sensory inputs, leading to more coherent and comprehensive interpretations of stimuli. This integration is crucial for recognizing patterns, such as identifying faces or objects, and contributes to the overall efficiency of sensory processing. Ultimately, neural convergence plays a vital role in how we perceive and respond to our environment.
Can neurotransmitters cross the synaptic cleft?
Yes, neurotransmitters diffuse across the synaptic cleft to transmit a neural signal; the actual neural impulse(spike) occurs when the neuron fires in response to a sufficiency of signals received.
Why is there muscle weakness after a stroke?
When there is apparent muscular weakness after a diagnosed stroke, the problem typically is not with the muscle, but with interruption of the neural pathways that access the muscle in question. As the stroke has killed off some of the neural connections to that muscle or muscles, weakness will appear until (and if) a sort of "re-routing" occurs and neural pathways are established once more.
What causes neural encroachment?
Neural encroachment occurs when neural tissue invades or affects adjacent structures, often due to pathological conditions such as tumors, inflammation, or injury. This encroachment can lead to compression or disruption of normal neural function, resulting in various neurological symptoms. Factors such as the growth characteristics of tumors or the extent of inflammatory processes can influence the degree of encroachment. Understanding these mechanisms is crucial for developing effective treatment strategies.
When Information is delivered within the CNS simultaneously by different -parts of the neural pathway is what process?
Convergence is the process by which information from different parts of the neural pathway is delivered simultaneously within the central nervous system (CNS). This integration of signals allows for complex processing and coordination of information within the CNS.
What is neural recruitment?
What is neural recruitment
A collection of genetically identical cells that are permanently associated but in which little or no integration of cell activities occurs?
colonial organism
Body regulation occurs at 3 levels.localneuralhormonal.in many cases the same result occurs but through a different mechanism.why does this happen and what are some exapmles of other body regulations.?
Negative feedback, positive feedback, and neural control.
