Drugs and Crime - Neurotransmitters - Assignment ExampleThe brain as an entry of the CNS is the midpoint of control in the body that has three main components brainstem, forebrain and the hindbrain. The forebrains responsibility is stretched several(prenominal) functions such as thinking, understanding, perceiving, reception and sensory information processing among others. Some of the body structures forming it include thalamus, hypothalamus, cerebrum and the cerebral pallium (Nieuwenhuys, 2008). The hind and midbrain from the brainstem. Visual and auditory responses argon carried out in the midbrain. About the hindbrain, it stretches from the spinal cord. It holds structures that move on it such as the cerebellum and the pons. This region is vital for the maintenance of equilibrium and balance, coordination and conducting the sensory information. The medulla oblongata is also in the hindbrain, responsible for automated functions such as heart rate, digestion and breathing.The spin al cord is also a structure in the central nervous system it takes a cylindrical form of bundled nerve fibres that are attached to the brain, running in the protective column that extends from the neck. Its nerves relay external stimuli to and from the brain.Body cells contain neurons and are the basic units of the CNS, they hold nerve processes which consist of dendrites and axons to transmit and conduct signals. Axons ferry signals outside the cell body, slice dendrites do the reverse (Nieuwenhuys, 2008). Neurons are further classified as sensory or motor, inter-neurons. The motor neurons charge information from the CNS to glands, muscles and organs while the sensory neurons carry information to the CNS from external or internal stimuli. Signals between the sensory and motor are relayed by the inter-neuronsThe synapse is the gap between the axon and dendrites that holds the synapse quiet where axon releases the neurotransmitters.Neurotransmitters are mostly associated with dop amine and schizophrenia.
