What is the tiny space between each axon tip and the next dendrite or muscle called?
The tiny space between each axon tip and the next dendrite or muscle is called a synapse. At the synapse, electrical signals from the axon are transmitted to the dendrite or muscle through the release of chemical messengers called neurotransmitters.
Describe parts of the neuron?
DENDRITE, SOMA, and AXON are the main parts of a neuron. Neurons signal one another via chemicals called NEUROTRANSMITTERS released at SYNAPSES. DENDRITES are usually the RECEIVING part, SOMA is the body of the neuron where the DNA is and most of the metabolic activity occurs, and AXON is the OUTPUT portion of the neuron. There can be many many DENDRITES, depending on the type of neuron, and the AXON can divide near its end and have some number of AXON TERMINALS. Neurons 'connect' at SYNAPSES (without exactly 'touching', that is without merging their cell membranes and sharing cytoplasm , and are held in place by SYNAPTIC ADHESION MOLECULES which protrude from each side of the synapse and stick to one another, binding the parts of the synapse together). A SYNAPSE is a tiny GAP between neuron structures (typically an AXON of one neuron and a DENDRITE of another), where the neural signal is conveyed from one neuron to the next via chemicals called NEUROTRANSMITTERS. A neuron signals another neuron in this way: as a neuron FIRES, an ACTION POTENTIAL is caused to move along the axon; when it reaches an AXON TERMINAL it causes tiny bags called VESICLES to merge with the cell membrane and release NEUROTRANSMITTERS into the SYNAPTIC gap (or CLEFT) between the neurons, where the neurotransmitters diffuse quickly to the post-synaptic DENDRITE. The dendrite has LIGAND-GATED ION PORES which have structures which receive the neurotransmitters, like a key into a lock, which then causes the pores to open and allow sodium ions into the dendrite. These sodium ions can then BEGIN this same process in that next neuron, if ENOUGH signals are received to TRIGGER its firing. A neuron can be TRIGGERED to FIRE if either MANY dendrites receive signals (called SPATIAL triggering), or if one or more dendrites receive many signals in quick succession (called TEMPORAL triggering).
What is a tiny particale?
A tiny Particle is Called an Atom.
Where is the synaptic gap located?
The synaptic gap isn't a region of the brain itself, but a term used to describe the tiny space between an axon terminal and the axon or tissue it is communicating with; so synaptic gaps are spread right throughout both the central and peripheral nervous systems.
How are neurons able to generate tiny electrical currents?
Neurons are able to generate tiny electrical currents through a process called action potential. This occurs when the neuron receives a stimulus that exceeds a certain threshold. It triggers a rapid exchange of charged particles, or ions, across the cell membrane, resulting in an electrical impulse that propagates along the neuron's axon. This electrochemical signal allows neurons to communicate with each other and transmit information throughout the nervous system.
A synaptic knob would be located on a?
A synaptic knob is a tiny bulge at the end of a terminal branch of a presynaptic neuron's axon!
What is the tiny space between each axon tip and the next dendrite or muscle called?
The tiny space between each axon tip and the next dendrite or muscle is called a synapse. At the synapse, electrical signals from the axon are transmitted to the dendrite or muscle through the release of chemical messengers called neurotransmitters.
What is the function of synaptic knob of axon terminal?
"When a nerve impulse reaches the synaptic knob at the end of an axon, synaptic vesicles release a neurotransmitter that diffuses across the synaptic cleft and binds to specific receptors on the postsyanptic membrane" Above From:Hole's essentials of Human Anatomy & Physiology (tenth edition) page=220, figure9.9 Quick definition of the "Synaptic knob- Tiny enlargement at the end of an axon that secretes a neurotransmitter." Above From: Same book as before (Hole's essentials of Human...) page= 584 (Glossary)
What is the tiny space that lies between one axon and a dendrite?
Synapse.
The tiny space between the axon terminal and the dendrite of another neuron is called the?
Synaptic Cleft.

What are the tiny sacs found within the terminal button which release chemicals into the synapse?
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.
When a nerve impulse reaches the end of the axon the tiny sacs that store the neurotransmitters move to the surface and release the neurotranmistters These tiny sacs that store the neurotransmitters?
sacs are Synaptic vesicle.
What are men reproductive cells called?
Men's reproductive cells are called, "Spermatazoa" (spurm-uh-tuh-ZOE-uh) A single cell is called a, "Spermatazoon" (spurm-uh-tuh-ZOE-on) For short, both are often called, "Sperm cells". Sperm cells are very, very tiny, needing a microscope to even see them. They each have a long 'tail' called a flagellum used to swim to where they need to go.
How do you change the gear shift knob on a Mercedes 320 clk 99?
rotate the lower part of the knob " clockwise"....( i think , if not go the other way) it will loosens it up and uncover a tiny screw .
What are the components of a function?
The dendritic tree (to bind neurotransmitters (NTs)), the soma (also referred to as the cell body), the axon hillock (where action-potentials initiate), the axon (propagates the electrical signal), and the axon terminal (release of neurotransmitters). The membrane properties are also different to the average cell because they contain receptors and a high density of ion channels. Inside the cell, NTs are synthesized and 'shipped' down the axon to the axon terminal on long thin filaments propelled by tiny actin/dynein 'motors'. Once at the terminal, the NTs wait at the 'presynaptic active zone' for release (which is prompted by the electrical signal conveyed down the axon from the axon hillock).
