Cell Biology
This is when an integral channel protein is used to support molecules traveling from a high concentration to a low concentration.
What is facilitated diffusion?
Microbiology and cilia are found on this side of epithelium.
What is the apical side?
This type of cartilage is found in intervertebral discs and knee discs that have great tensile strength which allows it to absorb compressive shock.
What is fibrocartilage?
The scab detaches during this stage of tissue repair.
What is stage 3?
This fatty/waxy solid made of CHO bonds increases membrane stability.
What is cholesterol?
This is a form of endocytosis which means "cell-drinking"
What is pinocytosis?
Fibroblasts produce collagen fibers to bridge the gap and debris is phagocytized in this stage of tissue repair.
What is stage 2?
These long, cylindrical, multinucleate tissues have obvious striations and are attached to bone.
What is skeletal muscle tissue?
This epidermal layer is full of keratinocytes and intermediate filaments.
What is the stratum spinosum?
This type of cell junction is primarily involved in preventing the leakage of extracellular fluid across a layer of epithelial cells.
What are tight junctions?
This process breaks down glucose and converts it into 36-38 ATP molecules.
What is cellular respiration?
This is the name of the epithelial tissue layer in serous membranes.
What is mesothelium?
This type of muscle tissue propels substances or objects (foodstuffs, urine, a baby) along internal passageways, and are involuntarily controlled.
What are smooth muscles?
List at least 2 occurences during stage 1 of tissue repair.
• Severed blood vessels bleed.
• Inflammatory chemicals are released.
• Local blood vessels become more permeable, allowing white blood cells fluid, clotting proteins, and other plasma proteins to seep into the injured area.
• Clotting occurs; the surface dries and forms a scab.
The superficial fascia consists mainly of these cells.
What are adipocytes?
This organelle is the site of the citric acid cycle and oxidative phosphorylation.
What is the mitochondrion?
List the three types of gland secretion.
1). Merocrine
2). Holocine
3). Apocrine
These connective tissue cells store nutrient energy and provide insulation.
What are adipocytes?
This type of small muscle is attached to hair root, and is responsible for raising hair follices.
What is the arrector pili?
This is the only fluid connective tissue.
What is blood?
These molecules speed up chemical reactions in the cell without being consumed, and lower activation energy.
What are enzymes?
List the 5 characteristics of epithelial tissues.
1. Polarity
2. Specialized contacts
3. Supported by connective tissue
4. Avascular, but innervated
5. Can regenerate
These type of cells are found in the lacunae of hyaline cartilage.
What are chondrocytes?
This layer of the epithelium consists of actively dying organelles and nuclei.
What is Stratum Granulosum?
This type of molecule is most likely to easily diffuse across a cell membrane.
What are small, nonpolar molecules.
