Nervous tissue is composed of two types of cells, neurons and glial cells. Neurons are responsible for the computation and communication that the nervous system provides. They are electrically active and release chemical signals to communicate between each other and with target cells. Glial cells, or glia or neuroglia, are much smaller than ...
The development includes the process of cell differentiation, in which unspecialized cells become specialized in structure and function to perform certain tasks in the body. The development also includes the processes of growth and repair, both of which involve cell differentiation. Growth is the increase in body size.
30 de ene. de 2024 · Our nervous system is a complex network of diverse nerve cells or neurons, as well as glial cells, that work together to coordinate the system's overall function. Neurons are classified into different categories based on different criteria, such as morphology, function, connections and neurotransmitters.
Structure of Nerve Cell. The shape, size, and structure of nerve cells depend on their position and function in the body. Usually, the size of nerve cells varies depending on how long the electrical impulses are to be transmitted. The nerve cell is a specialized individual cell that forms our nervous system.
20 de mar. de 2022 · These hair cells convert the sound signals into nerve impulses that are carried by the cochlear nerve trunk to the brainstem and eventually to the brain, for interpretation. Overall, the cochlear nerve trunk contains over 30,000 sensory nerve fibers and is approximately 1 inch in length.
20 de sept. de 2020 · Thus, understanding how regenerating axons respond to their environment and direct their growth is essential to improve the functional outcome of patients with nerve lesions. Schwann cells (SCs) play a crucial role in the regeneration process, but little is known about their contribution to specific reinnervation.
21 de dic. de 2023 · Description: Spherical or polygonal central component of a neuron. Function: Integration and signal processing, protein synthesis, metabolic activities. Components: Nucleus (DNA), cytoplasmic organelles (endoplasmic reticulum (smooth and rough), Golgi apparatus, microtubules, mitochondria, lysosomes), axon hillock. Axon hillock.
