Do nerves contain axons?
Nerves are like trees. The have branches call axons.
What is the structure at the end of an axon that produces neurotransmitters?
The axon is a single process extending from the axon hillock, sometimes covered by a fatty layer called a myelin sheath that conducts nerve impulses away from the cell body of the neuron.Distal tips of axons are telodendria, each of which terminates in a synaptic knob.
Are dendrites and axons both armlike processes that extend from cell bodies?
Yes, it is true. Dendrites: Arm-like processes that extend from the cell body of all neurons which receive signals. They are short, tapering, and have branching extensions and are usually found close to the cell body. Dendrites are unmyelinated (slow conductors). Axons: Are single arm-like process that extends from the cell body of all neurons which generate and transmit nerve impulses. They can be long (up to ~ 1 meter) or short with diffuse branching at the end. Axons are myelinated (fast conductors).
How does the brain create connections between the microscopic cells?
Axons and dendrites make neuronal signal connections via synapses, which are small spaces between the output (axon) and inputs (dendrites) of neurons, through which chemicals released by axons, called neurotransmitters, diffuse to and stimulate new neural impulses in dendrites, thus functionallyconnecting the brains neurons.There are also small molecules called synaptic adhesion molecules which protrude from both the end of an axon and the beginning of a dendrite, into the synapse, which then stick to each another, thus holding the axon and dendrite in position together, although the cell membranes of the two neurons do NOT touch nor merge, and there is no exchange of cytosol between them.
A smooth rounded end of a bone is called?
A smooth rounded end of the bone is called a condyle.
What are the two kinds of branches that extend from the cell body of a neuron?
Terminal branches (aka end brushes) are at the end of a Motor Nerve (aka Efferent Nerve) and are in very close proximity to the muscle fibers.
What are the structures at the end of axons?
nerve
Why do you think axons are long?
Because they have to reach from the base of the spine to the end of the foot.
The inferior end of the trachea divides into the left and right what?
The trachea branches into the left and right airways at the carina. These branched airways are called the bronchi.
What is the tiny sacs found at the end of the branches?
They are called the aveolar sacs .they consists of aveoles and the exchange of gases takes place here.
How do you see love line on hand?
a straight line which insect branches at the end and branches are parallel
How do you actually do the drawing of a factor tree of the number 56?
put 56 as your top number on your tree. make two branches. make one branch have 14 at the end and one branch have 4 at the end. now make two branches on the end of 14 and make 2 on one of these branches and make 7 on one ofthese branches. now make two branches on the 4 branch. now make a 2 on the end of one of these branches and a 2 on the other one of these branches. sry if it is confusing. cant draw a real factor tree using the tool I have
Why are most leaves at the end of branches?
cause if they were at the start of branches, that would be one weird looking tree.
Do nerves contain axons?
Nerves are like trees. The have branches call axons.
What is the part of the neuron that carries signals and transmits them to other neurons?
The smaller, receiving, head end of a neuron is called the dendrite. This transmogrifies first into the nucleus containing cell body and then into the multi-branched transmission arms of the axon. Axons from the spine to the foot are up to a meter in length.
What is the functions of neurotransmitter?
The neurotransmitters are stored in tiny sac-like structures called vesicles at the end of axons. When an impulse, or nerve signal, reaches the end of the axon, the vesicles release a neurotransmitter into the small space between the adjoining cells (synaptic gap). Neurotransmitters diffuse across the synapse and bind to receptors in the receiving cell that are specific for the neurotransmitter.
What is the part of the respiratory system that has tiny air bags?
ok, think of your lungs as a cluster of grapes hanging upside down. The smallest branches are called bronchioles . At the end of each bronchiole is an "air sac" called alveoli .
