To pick up contributions from the field of molecular, classical and physiological genetics and from evolution and population biology is even more difficult. The general facets of current work in animal breeding may be classified into theoretical animal breeding, animal research and application.
In other cells, such as gland cells and ciliated cells, it is believed that the membrane voltage is important to the execution of cell function. The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types, the membrane generates an impulse as a consequence of excitation.This impulse propagates in both cell types in the same manner. What follows is a short introduction to the anatomy and physiology of nerve cells.ells are specialized in their anatomy and physiology to perform different tasks. All cells exhibit a voltage difference across the cell membrane. Nerve cells and muscle cells are excitable. Their cell membrane can produce electrochemical impulses and conduct them along the membrane.
Special sense receptors provide for taste, smell, sight, hearing, and balance. Nerves carry all messages exchanged between the CNS and the rest of the body. Back to top. CNS: neurons, brain, spinal cord. The neuron transmits electric signals like an electric wire. The perikaryon (cell body) is the neuron central part. Dendrites, short branches, extend from the neuron. These input channels receive information from other neurons or sensory cells (cells that receive information from the environment). A long branch, the axon, extends from the neuron as its output channel. The neuron sends messages along the axon to other neurons or directly to muscles or glands. Neurons must be linked to each other in order to transmit signals. The connection between two neurons is a synapse. When a nerve impulse (electrical signal) travels across a neuron to the synapse, it causes the release of neurotransmitters.
