| Term | Definition |
|---|---|
| Actin and myosin proteins in muscle in muscle movement | chemical energy and mechanical energy. |
| Skeleton Axial and appendicular | The axial skeleton is comprised of the skull ribcage and vertebrae. The appendicular skeleton includes our limbs, and pelvis which is attached to the axial skeleton. |
| Stratum Basal | This is where the layer of the dermis ends, and the epidermis layer begins. Keratinocytes are generated in the stratum Basale. These cells produce a tough outer layer. The cell division in this layer is rapid. Besides the keratinocytes there are also mela |
| Stratum Spinosum | Stratum spinosum is the next layer up the stratum and this layer is composed of desmosomes. Desmosomes connect to the keratinocytes which lose water and become spiky and shriveled up. Cells that we also find in this layer are immune cells. These Langerhan |
| Stratum Granulosum | keratinocytes become grainy with keratohyalin which is the protein which handles the protein keratin. Lamellar bodies are also released in this layer and form a lipid layer. The next layer is a thin clear layer called the stratum lucidum. This is where th |
| Stratum Corneum | all dead cells as well. It is flat layers of keratinocytes stacked together on top of each other and constantly shed off. The process is continuous. The nutrients and oxygen are provided from the dermis which is below all the layers of the epidermis |
| phospholipid bilayer of cell membrane | - tail of the phospholipid has no charge and no polarity it is hydrophobic. The head of the phospholipid is charged and goes well with water as it is polar called hydrophillic. The phospholipid is amphipathic. The head faces the inside of the cell, and |
| DNA | -stands for deoxyribonucleic acid -structure is a double strand made of deoxyribose and nucleic acid |
| Homeostasis | homeo-same stasis- standing still Positive and negative feedback system helps maintain homeostasis |
| Dorsal | The space that encloses the brain and spinal cord forms one continuous cavity |
