BIL 150 Lecture Notes - Lecture 21: Blastocoel, Osmoregulation, Citric Acid Cycle
Document Summary
Vertebrates have backbone, nerves encased in bones. 3 types of embryonic origins (all tissues derived from these) Origins of major vertebrate tissue= cell migrations. Initial blastocoel has single layer of cells. Fat/adipose, blood, cartilage, bone, fibrous connective, loose connective. Loose connective: loose weave of fibrous proteins. Ground substance: matrix of loose connective tissue. Tissues made of cells that conduct electrical impulses for communication. Large structure: cell body with dendrites coming out. Dendrites respond to the environment and change polarization of membrane. Serve as protection, support, structure for neurons. Systems of the 4 major tissue types. Metabolic rate: total energy used by organisms per unit time to do biological work. Animal bioenergetics: energy needed to do vertebrate physiology (run/etc) Vo2 max: determine with stress measuring equipment (diff values depending on method) Much of vertebrate energy used to maintain homeostasis. Similar to: signal transduction hypo: epinephrine binds to control center to create response/effect. Ex: andromeda movie based on real science.
