A hillock or knoll is a small hill, [1] usually separated from a larger group of hills such as a range. Hillocks are similar in their distribution and size to small mesas or buttes . This particular formation occurs often in Great Britain and China .
In heraldry, a mount (also mountain, hill, hillock) is a representation of a hill or mountain as a curved terrace in base. [1] When the mount is included in the lower part of the shield, it may be considered an ordinary rather than a charge.
The axon hillock is a specialized part of the cell body (or soma) of a neuron that connects to the axon. It can be identified using light microscopy from its appearance and location in a neuron and from its sparse distribution of Nissl substance .

The axon hillock is the area formed from the cell body of the neuron as it extends to become the axon. It precedes the initial segment. The received action potentials that are summed in the neuron are transmitted to the axon hillock for the generation of an action potential from the initial segment.
At the axon hillock of a typical neuron, the resting potential is around –70 millivolts (mV) and the threshold potential is around –55 mV. Synaptic inputs to a neuron cause the membrane to depolarize or hyperpolarize; that is, they cause the membrane potential to rise or fall. Action potentials are triggered when enough depolarization ...

The surge of depolarization traveling from the axon hillock to the axon terminal is known as an action potential. Action potentials reach the axon terminal, where the action potential triggers the release of neurotransmitters from the neuron. The neurotransmitters that are released from the axon continue on to stimulate other cells such as ...
