Life & Cell Cycles
This process of cell division results in two genetically identical daughter cells for growth and repair.
What is Mitosis?
This part of the neuron receives incoming signals from other cells and carries them toward the cell body.
What is a Dendrite?
Often called the "Master Gland," it secretes Growth Hormone and TSH under the direction of the hypothalamus.
What is the Pituitary Gland?
These are the three types of muscle tissue found in the human body.
What are Skeletal, Smooth, and Cardiac?
This organelle is known as the "powerhouse" of the cell because it generates ATP.
What is the Mitochondria?
Unlike somatic cells, gametes are referred to by this term because they contain only one set of chromosomes.
What is Haploid?
This division of the Autonomic Nervous System is responsible for the "Fight or Flight" response.
What is the Sympathetic Nervous System?
This hormone is released by the pancreas when blood glucose levels are too low, signaling the liver to release stored sugar.
What is Glucagon?
The "functional unit" of the respiratory system where gas exchange actually occurs with the blood.
What are the Alveoli?
These three macronutrients provide the body with energy (calories).
What are Carbohydrates, Fats, and Proteins?
During meiosis, this many daughter cells are produced, each with half the genetic material of the parent.
What is four?
These chemical messengers, such as dopamine or serotonin, cross the synapse to transmit signals between neurons.
What are Neurotransmitters?
This is the primary difference between endocrine and exocrine glands.
What is the presence of ducts? (Endocrine are ductless; Exocrine have ducts).
In the digestive system, most nutrient absorption happens in this specific organ.
What is the Small Intestine?
This birth control method is a small T-shaped device inserted into the uterus by a healthcare provider.
What is an IUD (Intrauterine Device)?
This structure, located above the testes, is where sperm are stored and allowed to mature.
What is the Epididymis?
Nerve impulses are sent electrochemically, relying heavily on the movement of these two specific ions across the membrane.
What are Sodium and Potassium?
This condition results from an overactive thyroid gland, often leading to a rapid heart rate and increased metabolism.
What is Hyperthyroidism?
This type of immunity involves B-cells producing antibodies to fight specific pathogens.
What is Adaptive (or Humoral) Immunity?
The hierarchy of biological organization starts with elements and molecules, which then form these basic units of life.
What are Cells?
In the stages of pregnancy, the developing human is referred to by this term from week 9 until birth.
What is a Fetus?
This region of the brain, containing the thalamus and hypothalamus, acts as the primary relay station for sensory info.
What is the Diencephalon?
This regulatory mechanism ensures that once a hormone reaches a certain level, the body stops producing more of it.
What is a Negative Feedback Loop?
The body's tendency to maintain a stable internal environment despite external changes.
What is Homeostasis?
This endocrine disorder involves a deficiency in or a resistance to the hormone insulin.
What is Diabetes Mellitus?
