BIOL 1010: Human Biology

Explore the effects of isotonic, hypertonic, and hypotonic solutions on plant and animal cells. Understand water movement, solute concentration dynamics, and the resulting cellular changes, including turgidity in plants and crenation or lysis in animals.

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity

Discover the intricate architecture of atoms, the fundamental units of matter. Highlighting the roles of electrons, protons, and neutrons, learn how they create the characteristic structure of atoms. This knowledge reveals the essence of the material world

Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.

Learn about the anatomy of the tibia, one of the lower leg bones, and discover how it's connected to the fibula through the interosseous membrane. Find out the correct answer regarding the tibia's structure and connections.

Explore the world of proprioceptors specialized sensory receptors in joints muscles and tendons that help us sense body movement and position. Understand the key types such as muscle spindles tendon organs and joint kinesthetic receptors. Learn why tactile discs are not considered proprioceptors even though they are sensory receptors
