Although they can be used for many reasons, contract surety bonds are most commonly used in the construction industry to ensure projects are completed according to contract. For this reason, contract bond and construction bond are often used interchangeably.
1: How does ecstasy work: serotonin pathways in the brain. The nerve pathway that is predominantly affected by ecstasy is called the serotonin pathway. Serotonin is a neurotransmitter that is synthesized, stored, and released by specific neurons in this pathway. It is involved in the regulation of several processes within the brain, including mood, emotions, aggression, sleep, appetite, anxiety, memory, and perceptions. Tell the students that you will show them how a chemical like serotonin can regulate these processes. First, describe how serotonin pathways innervate (connect to) different brain regions. Point to the cell bodies of the serotonin pathway that are located in the brainstem area the Raphe nucleus in pink).
The process of reuptake, for example, affects serotonin. Serotonin is a neurotransmitter (a chemical messenger). It is produced by nerve cells in the brain and is used by nerves to communicate with one another. A nerve releases the serotonin that it has produced into the space surrounding it. balance is reached for serotonin between attachment to the nearby nerves and reuptake. A medication that acts as a selective serotonin reuptake inhibitor (SSRI) blocks the reuptake of serotonin and thereby changes the level of serotonin in the brain. Reuptake is sometimes written as re-uptake.
