![]() ![]() Metabolic support – The neurones have a constant requirement for nutrients such as glucose but they are unable to store or produce glycogen themselves. ![]() They contain various neurotransmitters which are released into the synapses to allow signal transmission from one neurone to the next.Īstrocytes are star-shaped glial cells within the brain and spinal cord, depending on the method used they make up between 20 and 40% of all glial cells. These make synaptic connections with other neurones. Axon terminal – Distally the axon branches, forming axon terminals.Schwann cells – These insulate the axon with myelin sheath which facilitates the rapid transmission of action potentials along the axon.The action potentials are conducted along the axon to the axon terminal. Axon – It arises from the soma, specifically from an area called the axon hillock, where action potentials are initiated.They transmit signals received from other neurones to the soma. Dendrites – these processes originate from the soma and extend outwards.It also contains the Nissl Substance, which are granules containing rough endoplasmic reticulum and free ribosomes. Cell body or Soma – this contains the nucleus and the neurone’s intracellular organelles (such as the mitochondria and Golgi apparatus).The neurone is made up of several components: ![]()
