- How many pairs of chromosomes do male and female karyotypes have?
- What layer of the embryo develops into the epidermis and nervous system?
- the protrusion of a small loop of bowel through a weak place in the lower abdominal wall or groin; ring opens just right
- Which type of reproduction requires the fusion of gametes?
- What is each cell in embryonic cleavage called?
- How much sperm lack forward progression?

- The mechanism that re-polarizes axons by moving ions outside the membrane once the charge has evened.
- The name for chemicals that cause us to feel happy, sad, alert, etc.
- Sensory and Motor Neurons that connect to the Central Nervous System
- Brain and Spinal Cord; coordinates, controls, and responds.
- The primary ion inside the axon's membrane that, along with proteins, provide a polarized negative charge.
- Type of scan that puts one's head in a strong magnetic field that aligns spinning electrons of brain molecules, then disorients them with a radio wave. When they return to normal, it gives a detail picture of the soft tissues.
- Type of scan that targets the electrical waves in one's brain, down to a specific stimulus
- Type of scan that shows brains consumption of chemical fuel, such as glucose.
- A neural impulse; a brief electrical charge that travels down an axon
- The primary ion outside the axon's membrane that provide a polarized positive charge.
