Document Summary

1 chains of amino acids or a protein, are formed through translation by ribosomes in the endoplasmic reticulum. These ribosomes read strands of mrna and produce complementary amino acids into a chain. 2 these chains of amino acids are packaged in the golgi into vesicles. 3 these vesicles are then sent to down the axon to be secreted into the synapsis. Synapsis: this is the gap between the endfoot of one neuron and dendrites of another that. Dendrites cell body axon endfoot (presynaptic cleft) dendrites (postsynaptic cleft) Found in the cns (central nervous system) Makes the myelin sheaths that surround axon, this enhances conductivity. Gaps between the myelin sheaths are the nodes of ranvier: schwann cells. One endfoot connected to the capillaries (blood stream in order to access nutrients) One endfoot on the neuron (the neuron then takes nutrients like glucose to survive) Induction of bbb (blood brain barrier, which protects the brain and spinal cord from toxins)
