Efferent
The synapse is the space between pre- and post-synaptic neurons
afferent and efferent Afferent (to the spinal cord and brain) Efferent (to an effector such as a muscle or gland)
A Synapse is the space between two neurons or between a neuron and a receptor organ. A single neuron can have a few, or several hundred synapses.
The two major effects are excitatory and inhibitory. For example ACh leads to the post-synaptic cell's depolarization while GABA or glycine will hyperpolarize the post-synaptic cell. But this is all a simplification. Some synapses have an effect of neuromodulators sometimes released as a co-transmitter (e.g. NPY and epinephrine from sympathetic ganglionic neurons). In some situations the cotransmitter can have a mixture of effects.
Efferent
The two fibers that a neuron has are the nerve and the myelin fibers
They are call synapses, there are two types chemical and electrical.

The end of one neuron, the presynaptic button, sends messages to other cells by releasing neurotransmitters (chemical messengers) into the synaptic cleft (a small space between two neurons). The other cell, whether it be a neuron, a muscle, a sweat gland, etc., will receive this message at the post synaptic membrane of its cell, and will respond accordingly.
Without the use of any apps, no, you cannot send or receive picture messages on the iPod touch.If you have an iPod touch, there are two apps that let you SEND picture message, but you cannot RECEIVE picture mail. The name of the apps are:Fun MailText Now (Free Version)
There are two tabs for messages. Click on your normal tab and then look just behind it for 'other'. Normally this is where people can send you messages who aren't in your friends list or those who you haven't contacted can leave a message. You can choose to view and accept any messages or not.
