Clusters of neuronal cell bodies and dendrites in the brain are called nuclei.
Yes, dendrites contain Nissl bodies. Nissl bodies, also called Nissl substance or Nissl granules, are rough endoplasmic reticulum in the neuronal cell bodies and dendrites. They are responsible for protein synthesis in the neuron.
Clusters of neurons cell bodies are called ganglia in the peripheral nervous system and nuclei in the central nervous system. Ganglia contain the cell bodies of sensory or motor neurons, while nuclei contain cell bodies of interneurons or projection neurons.
Groups of neuronal cell bodies in the central nervous system (CNS) are called nuclei. These nuclei are clusters of cell bodies that are involved in specific functions such as processing sensory information or controlling motor movements. Examples include the thalamus and basal ganglia in the brain.
Solar plexus.
Asteroid belts are not individual celestial objects themselves, but rather regions in space between planets that contain numerous small rocky bodies called asteroids. These belts are typically located in the inner regions of the solar system, such as between Mars and Jupiter.
Lysosomes
Some oceans contain areas which have their own names, such as the Sargasso Sea, in the Atlantic. But normally this is applied to regions marked by landforms. or adjacent to them.Flows of water within large bodies are called currents.(see the related question below)
Cell bodies in neurons are called soma or perikaryon. They contain the nucleus and most of the organelles responsible for the cell's metabolic activities.
Yes, they are called spicules, not pores or spiracles as many people think.
Synapses. Net flow of charged ions ("impulses") in neuronal cells trigger additional ion flow (ionotropic signaling) or neurotransmitter release (metabotropic signaling) to both neuronal and non-neuronal cell types ("the body") at junctions called synapses.
No, heat naturally flows from hot bodies to cold bodies in a process called heat transfer. This is described by the second law of thermodynamics, which states that heat flows spontaneously from higher temperature regions to lower temperature regions.
