Heroine: This is a drug where the dopamine and inhibitory neurotransmitters are affected. The inhibitory neurotransmitters are shut down and without the inhibition the dopamine is released. This drug is like a painkiller that really can be very dangerous and could damage your body for long periods of time.

Ecstasy: Ecstasy interferes with the serotonin transmitters. The drug becomes trapped in the synaptic cleft. It then binds again with the receptors of the cell. The drug affects many emotions and it is partially addictive which can lead to an addiction for many.

Marijuana: Marijuana interferes with the inhibitory neurotransmitters. Without the inhibition of the inhibitory neurotransmitters, dopamine can be released. Marijuana affects the person by slowing down movement and making them feel calm and relaxed. This is a drug that is used for medicinal purposes and can be used medically for certain treatment.

Methamphetamine: Meth affects the dopamine transmitters. The meth then enters the dopamine vesicles kicking out the dopamine neurotransmitters. The drug makes the user feel intense pleasure which then causes the meth to be highly addictive.

Alcohol: The gaba inhibitory neurotransmitter is affected by alcohol and glutamate. The gaba receptors make the brain even more inhibitory. Stops glutamate from exciting the cell. The drug alcohol affects memory, decision making, and impulse control. The frontal lobe is highly affected by this.

Cocaine: The dopamine neurotransmitters are affected by cocaine. Cocaine blocks dopamine transporters which then causes the cell to be overstimulated, through the binding of receptors. This causes the users to be fidgeting or able to be still. Cocaine is a powder that is a bunch of mixed chemicals together creating a compound that stimulates the brain and it is cocaine.

LSD: LSD interferes with the serotonin neurotransmitters. LSD has very complex sensory effects because it can inhibit or can excite the receptors in the brain. This drug affects the wakefulness and evokes a startling response to unexpected stimulus.

Abducens nerve:(Motor) The abducens nerve is the sixth cranial nerve that controls the movement of the lateral rectus muscle of the eye.It is also part of the Central Nervous system.

Facial nerve: (mixed) The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue. The nerve typically travels from the pons through the facial canal in the temporal bone and exits the skull at the stylomastoid foramen. It arises from the brainstem from an area posterior to the cranial nerve VI and anterior to cranial nerve VIII

Trigeminal nerve:(mixed) The trigeminal nerve is part of the central nervous system which sends sensory signals from the face to the brain. It is the fifth cranial nerve and is divided into 3 parts ophthalmic, maxillary, and mandibular division. The mandibular division also has motor functions. The function of this nerve is it helps in biting, chewing, swallowing, and facial and scalp sensations.

Trochlear nerve:(motor) The trochlear nerve , (lit. pulley-like nerve) also known as the fourth cranial nerve, cranial nerve IV, or CN IV, is a cranial nerve that innervates a single muscle - the superior oblique muscle of the eye The trochlear nerve is the fourth and smallest cranial nerve, but it has the longest journey inside the skull.

Vestibulocochlear nerve:(Sensory) The vestibulocochlear nerve is the eighth cranial nerve that connects the inner ear to the brain. It is part of the PNS

Oculomotor nerve :(motor) The oculomotor nerve is the third cranial nerve (CN III) that enables eye movements, such as focusing, pupil constriction and eye torsion.

Glossopharyngeal nerve:(mixed) The glossopharyngeal nerve, also known as the ninth cranial nerve, cranial nerve IX, or simply CN IX, is a cranial nerve that exits the brainstem from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve. It controls Taste sensations from the rearmost third of the tongue. Also Sensations from the tonsils, back of the throat, middle ear, and the area behind the ear.

Optic nerve:(sensory) The optic nerve is a vital link between your eyes and your brain, carrying electrical impulses that let you see.

Vagus nerve :(Mixed) The vagus nerve is a superhighway of communication between your brain and your body, affecting your mood, digestion, heart, and immunity. It is part of CNS. It controls Digestion,Heart, Immune system, Respiratory rate, Speech.

Olfactory nerve: (Sensory) The olfactory nerve, also known as the first cranial nerve, cranial nerve I, or simply CN I, is a cranial nerve that contains sensory nerve fibers relating to the sense of smell. The afferent nerve fibers of the olfactory receptor neurons transmit nerve impulses about odors to the central nervous system (olfaction)

(Spinal) Accessory nerve: (Motor)The spinal accessory nerve is the eleventh cranial nerve and is composed of two parts, the cranial part and the spinal part. The spinal part originates from the sixth and seventh cervical vertebrae and enters the cranial cavity through the foramen magnum. The spinal accessory nerve is a purely motor nerve that innervates the sternomastoid and trapezius muscles in the neck. These muscles allow the head to tilt and rotate, and the shoulder to shrug and move.

Hypoglossal nerve: (Motor) The hypoglossal nerve, also known as the twelfth cranial nerve, is a motor nerve that controls the muscles of the tongue. It innervates all the extrinsic and intrinsic muscles of the tongue except for the palatoglossus, which is innervated by the vagus nerve. The tongue's extrinsic muscles help it move in different directions, while the intrinsic muscles help it make movements such as curling the tongue.

With the development of electrophysiology and the discovery of electrical activity of neurons, it was discovered that the transmission of signals from neurons to their target tissues is mediated by action potentials. An action potentialis defined as a sudden, fast, transitory, and propagating change of the resting membrane potential.

A nerve impulse, also called an action potential, is an electrical charge that travels along the membrane of a neuron. It is generated in response to a stimulus. The impulse is relayed along the axon of the nerve cell, bringing a message that instructs an effector to act. This transmission of a nerve impulse across the neuron membrane as a result of a change in membrane potential is known as Nerve impulse conduction.

The spinal cord is a long, cylindrical structure that connects the brain and lower back. It is surrounded and protected by a bony column of vertebrae.

The spinal cord is composed of nerve fibers that send and receive signals along tracts towards and away from the brain. It helps carry electrical nerve signals throughout the body.

There are 31 pairs of spinal nerves, each pair with a sensory root and a motor root. The spinal cord functions in information transmission and reflex coordination.

Brainstem: The medulla oblongata, pons, midbrain

Cerebrum: Biggest Part of the brain that controls a lot of your nerve decisions and choices.

Cerebellum: Smaller part of the brain that controls muscle movement

Arachnoid mater: middle between the pia mater and the dura mater

Pia Mater: the thinnest and last mater below the dura and arachnoid

Unipolar neurons: These neurons have a single long axon that is responsible for sending electrical signals. ...

Multipolar neurons: These neurons are able to receive impulses from multiple neurons via dendrites. ...

Bipolar neurons: These neurons send signals and receive information from the world. ...

Pseudo-unipolar neurons: These neurons relay signals from the skin and muscles to the spinal cord.

Nervous tissue is the main tissue component of the nervous system, which regulates and controls body functions and activity. Nervous tissue consists of two types of cells: neurons and neuroglia. Neurons are specialized for transmitting and processing nerve impulses. Neuroglia are supporting cells that provide nutrients and protection to neurons. Nervous tissue is subdivided into the central nervous system (CNS) and the peripheral nervous system (PNS).

The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The PNS is further subdivided into nerves, the autonomic system, and the somatic system. The autonomic nervous system is further subdivided into the parasympathetic and sympathetic nervous systems. The enteric nervous system is an independent subsystem of the PNS.
