Sensory neurones coma interneurons and the motto memes |
|
|
What are the two functions of synapses |
Transmission or blocking of impulses from one neuron to another |
|
|
What are the two types of synapses and which one is unidirectional |
The two types of synopsis include electrical and chemical synopsis electrical synapses is a direct open fluid channel that conduct electricity from one cell to another how chemical synapses transmit impulses only in one direction |
|
|
How many neurones does the central nervous system contain |
It contains hundreds of billions of neurones |
|
|
Which of these synapses is contained only in few quantities |
Electrical synapses |
|
|
List for excitatory neurotransmitters |
Norepinephrine acetylcholine glutamate aspartate |
|
|
List three inhibitory neurotransmitters |
Glycine dopamine serotonin garba |
|
|
Membranes of the postsynaptic neurones have receptor proteins which have two important functions |
Binding components: this protrudes outside from the membrane and into the synaptic cleft then it's buying the neural transmitter Ionophore components: it surpasses all the way through the postsynaptic membrane to the interior of the postsynaptic neurone |
|
|
How many neutrons does the brain contain |
Several thousands of billions of neutrons |

|
The human brain receives nerve impulses from |
31 pairs of spinal nerves and 12 cranial nerves |
|
|
The cerebrum is the largest part of the brain responsible for all mental activities such as thinking feeling and emotion what divides the cerebrum |
It is divided by a deep crevices callef the longitudinal sulcus . the longitudinal sulcus separates the cerebrum to the right and left hemispheres. the two hemispheres are connected by a bundle of myelinated nerve fibres called the corpus callosum |

Temporal lobe |
|
|
Where is the medulla located |
The medulla is part of the brainstem which is located just above the spinal cord |
