Biology Concepts

Front

Pathogens

Back

Tiny organisms like bacteria and viruses.

Front

Endocrine system

Back

The system of groups of glands in the body that create and produce hormones. The nervous system is faster.

Front

Pancreas

Back

Produces insulin.

Front

Motor neurons

Back

Receives the impulse from an interneuron and causes a response in an effector organ (muscle or gland). Part of the peripheral nervous system.

Front

Synapse

Back

The gap between two neurons. Impulses reach the vesicles containing neurotransmitters and get sent across.

Front

Interneuron

Back

Carry impulses through the spinal cord and brain (central nervous system) and gives impulses to motor neuron.

Front

Sensory neurons

Back

Detect changes and create impulses and send them to the interneuron.

Front

Endotherms

Back

Able to regulate body temperature by producing heat within.

Front

Ectotherms

Back

Relies on the environment to regulate body temperature.

Front

Negative feedback loop

Back

Process that keeps variables such as body temperature stable by correcting changes.
