A specialized junction between two neurons where nerve impulses are transmitted.

The space between the presynaptic and postsynaptic neurons where neurotransmitters diffuse.

A bulb-like structure at the end of an axon that stores and releases neurotransmitters.

A type of neuron that carries sensory information from receptors to the CNS.

A type of neuron that carries motor commands from the CNS to muscles and glands.

A type of neuron that connects sensory neurons to motor neurons and other interneurons within the CNS.

A chemical messenger released from the synaptic knob that binds to receptors on the postsynaptic neuron.

The process of maintaining a stable internal environment in an organism despite external changes.

Actions that are controlled by our conscious mind, like picking up a pencil or walking

Actions that happen automatically, without conscious control, like blinking or breathing

A pathway that allows a reflex action to occur quickly and automatically, bypassing the brain

A part of the body that receives commands from the nervous system and carries out an action, such as a muscle or gland

The process of receiving stimuli, processing information, and generating an appropriate response

The communication network that coordinates and controls bodily functions using electrical impulses and chemical signals

Adrenaline, a hormone secreted by the adrenal glands, increases glucose levels in the blood. This provides energy for fight or flight responses.

Adrenaline constricts blood vessels in the skin and digestive system, redirecting blood to the brain and muscles. This enhances oxygen delivery for crucial functions during emergencies.

Adrenaline increases heart rate, delivering oxygen to the brain and muscles faster. This accelerates metabolic activity and provides more energy for dealing with danger.

Insulin is a hormone that regulates blood sugar levels by reducing the concentration of glucose in the blood.

Testosterone is a hormone responsible for the development of male secondary sexual characteristics.

Steroid hormones, such as testosterone, that stimulate the building of large molecules from smaller ones, like protein from amino acids.

The outer layer of skin that provides a protective barrier.

The inner layer of skin responsible for providing strength and flexibility.

A process that narrows blood vessels, reducing blood flow and heat loss from the body.

A process that widens blood vessels, increasing blood flow and heat loss from the body.

The part of the brain that regulates body temperature and sends messages to other parts to adjust temperature.

The ability to maintain a stable body temperature despite external changes.

Insulin is a hormone that lowers blood glucose levels by promoting glucose uptake by cells, stimulating glycogen storage in liver and muscle, and converting excess carbohydrates into fat.

Adrenaline is a hormone released by the adrenal glands in response to stress or danger. It prepares the body for action by increasing heart rate, blood pressure, and breathing rate, constricting blood vessels in certain areas, and converting stored energy sources into usable fuel.

Glucagon is a hormone, secreted by the pancreas, that raises blood glucose levels by stimulating the liver to break down stored glycogen into glucose.

Type 1 diabetes is an autoimmune disease where the pancreas cannot produce enough insulin, leading to high blood glucose levels.

Insulin cannot be taken orally because it is a protein that will be digested by enzymes in the stomach and small intestine before it can reach the bloodstream.

Symptoms of diabetes include extreme thirst, frequent urination, fatigue, weight loss, and blurred vision. It can also lead to tissue damage in the long term.

Treatment of diabetes includes managing blood sugar levels through diet, exercise, monitoring blood sugar levels, and insulin injections.

Diabetes is a metabolic disorder characterized by high blood glucose levels. It occurs either due to the body's inability to produce enough insulin or the body's inability to use insulin effectively.

A mechanism that maintains stable internal conditions in the body despite external changes. It involves a series of steps to detect deviations, send signals, and trigger corrective actions.

A hormone secreted by the pancreas that helps lower blood glucose levels by promoting the uptake of glucose by body cells and the conversion of glucose into glycogen for storage in the liver.

A hormone secreted by the pancreas that helps raise blood glucose levels by stimulating the breakdown of glycogen stored in the liver, releasing glucose into the bloodstream.

A hormone produced by the adrenal glands that is released in response to stress or danger, preparing the body for 'fight or flight' response.

The increased rate of breathing that occurs as a result of adrenaline release during a stressful situation, allowing for greater oxygen intake.

The rapid heart beat that results from adrenaline release during stress, delivering oxygen-rich blood to the brain and muscles.
