A synapse is a gap between one neuron and another. To communicate, a neurotransmitter has to be made and then used as a tool to stimulate the second neuron.
Synapses contain synaptic vesicles and other organelles such as the mitochondria.
Chemical neurotransmitters are manufactured by neurons in the main part of the cell, then stored in little bundles called synaptic vesicles and transferred to the synapses. They are then released into the space between the two neurons.
One type of neurotransmitter may stimulate and another type may be the opposite.

What happens during synapsis in meiosis?
During synapsis in meiosis, homologous chromosomes pair up along their lengths to form tetrads. This is essential for crossing over to occur, where genetic material is exchanged between chromatids. Synapsis helps increase genetic diversity by introducing new combinations of alleles.
What happens during synapsas in meiosis?
The purpose of synapsis in meiosis is to increase genetic variability. It does this as the homolog pairs match up, which means there are 4 chromosomes of like, but possibly unique, DNA data in the grouping. This allows the cell. as it proceeds through Anaphase 1 and Anaphase 2 to separate the individual chromosomes first into 2 pairs then as individuals, which inturn adds to the variability as 1 chromosome goes to each daughter cell. .
When does crossing over occur in this meiosis?
Crossing over occurs during synapsis, prophase I.
Synapsis and crossing over occur during?
Synapsis and crossing over occur during prophase I of meiosis. During synapsis, homologous chromosomes pair up and exchange genetic material, a process known as crossing over, which increases genetic diversity.
Which event occurs during phosphate?
Phosphate is not a period of time during which an event can occur.
What is the pairing of homologous chromosomes during meiosis?
synapsis
What happens during synapsis meiosis?
Tetrads form
The most important occurrence during prophase one of meiosis which doesnt occur in prophase of mitosis is?
Crossing over, also known as genetic recombination, is a unique event that occurs during prophase I of meiosis but not during prophase of mitosis. It involves the exchange of genetic material between homologous chromosomes, resulting in genetic diversity among offspring.
What major chromosomal event occurs between leptonema and zygonema?
After condensing into long strands in the nucleus during Leptotene/Leptonema Chromosomes line up approximately with each other into homologous pairs. Telomeres cluster at one end of the nucleus and synapsis (pairing together of the homologous chromosomes) takes place in Zygotene/Zygonema.
The formation of a tetrad during meiosis occurs as a result of?
The formation of a tetrad during meiosis occurs as a result of homologous chromosomes pairing up and aligning with each other. This alignment allows for the exchange of genetic material between the homologous chromosomes through a process called crossing over, promoting genetic diversity.
The pairing of homologous chromosomes during meiosis is called what?
synapsis
Which step only occurs during meiosis?
One step that only occurs during meiosis is synapsis, where homologous chromosomes pair up and exchange genetic material through a process called crossing over. This occurs during prophase I of meiosis, allowing for increased genetic diversity in the resulting gametes. This step does not take place during mitosis, where chromosomes do not pair in this manner.
