homeostasis The steady-state physiological

condition of the body.

One of the many types of

balanced homeostasis are the

levels of pH.

negative feedback

loop

A primary mechanism of

homeostasis, whereby a change in a

physiological variable that is being

monitored triggers a response that

counteracts the initial fluctuation.

It is a brain based mechanism that gives the brain messages for it to respond to a negative situation, physically.

positive feedback

loop

A physiological control mechanism

in which a change in some variable

triggers mechanisms that amplify

the change.

It is the change of certain parts of your body through your brain.

neuron A nerve cell; the fundamental unit

of the nervous system, having

structure and properties that allow it

to conduct signals by taking

advantage of the electrical charge

across its cell membrane.

It is a crucial brain cell that transports thoughts and the primary of the nervous system.

sensory neuron A nerve cell that receives

information from the internal and

external environments and transmits

the signals to the central nervous

system.

It is the brains messenger as it sends signals from neurons.

interneuron An association neuron; a nerve cell

within the central nervous system

that forms synapses with sensory

and motor neurons and integrates

sensory input and motor output.

A highway through the brains neuron system, and it transports through major cells.

motor neuron A nerve cell that transmits signals

from the brain or spinal cord to

muscles or glands.

Even though signal travel through so many parts of the brain the motor neuron is the one responsible for talking to the body.

action potential A rapid change in the membrane

potential of an excitable cell, caused

by stimulus-triggered, selective

opening and closing of voltage-

sensitive gates in sodium and

potassium ion channels.

I sudden change in the brains membrane of potential that opens the brains voltage areas.

axon A typically long extension, or

process, from a neuron that carries

nerve impulses away from the cell

body toward target cells.

It is the transmission and changes carrier for the neurons.

dendrite One of usually numerous, short,

highly branched processes of a

neuron that conveys nerve impulses

toward the cell body.

A branch that breaks into the body to transport charges or commands to the body from the neurons.

neurotransmitter A chemical messenger released

from the synaptic terminal of a

neuron at a chemical synapse that

diffuses across the synaptic cleft

and binds to and stimulates the

postsynaptic cell.

A tiny chemical that travels through certain part of the brain and works a key to open gates and it is involved in creating pleasure.

synapse The locus where one neuron

communicates with another neuron

in a neural pathway; a narrow gap

between a synaptic terminal of an

axon and a signal-receiving portion

(dendrite or cell body) of another

neuron or effector cell.

Neurotransmitter molecules

released by synaptic terminals

diffuse across the synapse, relaying

messages to the dendrite or effector.

When it is time for a two neurons to communicate through the synapse to send messages or transmitters.

receptor On or in a cell, a specific protein

molecule whose shape fits that of a

specific molecular messenger, such

as a hormone.

As lock and key the receptor waits for that molecule that fits it to take action.

vesicle A small, intracellular membrane-

bound sac.

It is a small organ that is found in all cells.

inflammation A line of defense triggered by

penetration of the skin or mucous

membranes, in which small blood

vessels in the vicinity of an injury

dilate and become leakier,

enhancing the infiltration of

leukocytes; may also be widespread

in the body.

When a foreign item breaks in through the first layer of skin bacteria gets in, in order to protect its system from invasion cells attack in result of inflammation.

fever is a common medical sign

characterized by an elevation of

temperature above the normal range

of 36.5–37.5 °C (98–100!°F) due to

an increase in the body temperature

regulatory set-point.[2] This increase

in set-point triggers increased

muscle tone and shivering.

A fever is the attack of a virus that is foreign to the body, and it is in a process of heat to kill that virus.

skin Skin is the soft outer covering of

vertebrates.

The first layer of defense of the human body.

passive immunity Passive immunity is the transfer of

active humoral immunity in the

form of readymade antibodies, from

one individual to another.

It is using previous or familiar material from another individual to destroy a foreign bacteria or virus.

active immunity Immunity is a biological term that

describes a state of having sufficient

biological defenses to avoid

infection, disease, or other

unwanted biological invasion. In

other words, it is nothing but the

capability of the body to resist

harmful microbes from entering the

body. Immunity involves both

specific and non-specific

components.

It is the bodies natural and powerful ability to take care of foreign individuals without the need of medicine or other type of vaccine.

bacteria One of two prokaryotic domains,

the other being the Archaea.

A prokaryotic cell that infiltrates in the body to reproduce in an malignant or positive way.

virus A submicroscopic, noncellular

particle composed of a nucleic acid

core and a protein coat (capsid);

parasitic; reproduces only within a

host cell.

A small non-living thing that requires another to reproduce, for example

from the body fluids of living hosts.

A dominant specie or virus that takes over another to reproduce itself or survive.

memory T cell A clone of long-lived lymphocytes,

formed during the primary immune

response, that remains in a lymph

node until activated by exposure to

the same antigen that triggered its

formation. Activated memory cells

mount the secondary immune

response.

It recollects the foreigns material data to understand it and remembers them forever so you can never get the same disease ever again.

killer T cell Natural killer T (NKT) cells are a

heterogeneous group of T cells that

share properties of both T cells and

natural killer (NK) cells.

The cell that destroys foreign substances or organisms.

helper T cell A type of T cell that is required by

some B cells to help them make

antibodies or that helps other T cells

respond to antigens or secrete

lymphokines or interleukins.

A t cell that helps make antibodies as a response.

B cell A type of lymphocyte that develops

in the bone marrow and later

produces antibodies, which mediate

humoral immunity.

A cell that provides aid through reproduction of antibodies to fight any of the substances or chemicals that the body is not familiar with.

memory B cell A clone of long-lived lymphocytes,

formed during the primary immune

response, that remains in a lymph

node until activated by exposure to
