The distal end of a neuron is the axon, an extension that arises from the soma (cell body), and at the distal end of an axon there are extensions called telodendria. At the distal ends of telodendria are knoblike structures called synaptic end bulbs (sometimes called synaptic knobs). Synaptic end bulbs have synaptic vesicles inside them that contain neurotransmitters. Synaptic vesicles are released by exocytosis into the synaptic cleft for diffusion.
I can't tell from the way your question is worded if you're asking about axons, telodenria or synaptic end bulbs because all of these structures are at the distal end of a neuron. Determine what the function of the "extensions" is and use whichever part of my answer applies.
Motor neuron
at its distal end the tibia expands to form a prominence on the inner ankle called the
medial malleolus
Axon terminal
Each phalanx that articulates with the distal end of a metacarpal is a proximal phalanx. These phalanges are numbered one through five to distinguish them.
The receptor is the part of the neuron (usually a dendrite) that detects a stimulus. Dendrites are extensions of the main cellular body of the neuron called the soma; the impulse is passed on to another neuron at the other end, which is called the axon. Neurons transmit impulses to each other via electro-chemical connections to each other that are known as synapses.
No, the lateral malleolus is the distal end of the fibula. The medial malleolus is the distal end of the tibia.
The same as the slender, pointed projection on the distal end of the radius: the styloid process
The anterior surface of the distal end of the pancreas is located adjacent to the stomach, the duodenum, and the spleen. This area is called the pancreatic head, and it lies in close proximity to several vital digestive organs.
Neurotransmitters are stored in small sacs called vesicles located at the end of the axon terminal in a neuron.
A fracture involving the distal end of the radius and ulna is commonly referred to as a distal radius and ulna fracture. It can also be called a distal forearm fracture. This type of fracture often occurs as a result of a fall onto an outstretched hand.
The ulna has the head at the distal end. Usually the head of a bone is located at the proximal end. The ulna has a large process called the olecranon process that people call their 'elbow'.
