| Question | Answer |
|---|---|
| What are the 4 major tissue types? | Epithelial, Connective, Muscle, & Nervous tissue |
| Describe Epithelial Tissue | Covers and protects all body surfaces Example: epidermis |
| Describe Connective Tissue | Binds, protects, and serves as framework Example: dermis |
| Describe Muscle tissue | Contracts producing body movement Example: heart |
| Describe Nervous tissue | Sends electrical impulses regulating body functions Example: brain |
| What type of cells are found in melanin? | Melanin made by epidermal cells called melanocytes that give the skin, eyes, and hair pigment. |
| Describe Pheomelanin | A red/yellow pigment that's responsible for the color of skin, hair, and eyes in living organisms |
| Describe Eumelanin | A brown-black pigment that's responsible for the color of skin, hair, and eyes in living organisms |
| How many bones does the human body contain and what are they composed of? | 206 bones There are 80 bones of the axial skeleton, and 126 bones of the appendicular skeleton. |
| What are Bones composed of? | Bones are composed of many things such as minerals: calcium, phosphate, magnesium, sodium, and potassium, and collagen |
| Membranes are only found in __________ and _________. | Connective and Epithelial tissues |
| What types of membranes are found in connective and epithelial tissues? | Cutaneous, Serous, Synovial, and Mucous membranes |
| Explain the function of Cutaneous membranes. | Covers the body (skin) |
| Explain the function of Serous membranes. | Lines closed body cavities |
| Explain the function of Synovial membranes. | Lines the joints |
| Explain the function of Mucous membranes. | Lines organs leading to the outside of the body |
| Composed Entirely of Connective Tissue | Synovial membranes |
| Lining of throat, mouth, nose and secretes mucus | Mucous membranes |
| Serous membranes | Reduces friction, Covers organs Thorax and Abdomen Secretes Serous fluid |
| List the type of joints. | Fibrous, Cartilaginous, and Synovial |
| What is the degree of movement Fibrous joints makes within the body? | Synarthrotic: Immobile joints Example: Skull |
| What is the degree of movement Cartilaginous joints makes within the body? | Amphiarthrotic: Slightly moveable Example: Front of hip |
| What is the degree of movement Synovial joints makes within the body? | Diarthrotic Joint: Freely moveable Example: Shoulder, fingers |
| What are the types of ribs? | True Ribs (Vertebral Sternal), False Ribs (Vertebral Chondral ), and Floating Ribs (Vertebral ) |
| True ribs (vertebral-sternal) | The first 7 pairs that attach to the thoracic vertebrae and are connected directly to the sternum. |
| False Ribs (vertebral chondrall) | The 8th to 10th pair connected to the sternum through cartilage of the rib above. |
| Floating Ribs (Vertebral ribs ) | 11 -12 ribs do not attach to the sternum at all just the vertebra |
| What shapes are epithelial cell types? | Squamous (flat), Cuboidal (cube shape) or Columnar (column/tall rectangular shaped) shaped. |
| Where can Cuboidal shaped Epithelial Tissue be found in the body? | Glandular tissue and kidney tubules |
| Where can Columnar shaped Epithelial Tissue be found in the body? | The lining of the stomach and intestines |
| Where can Squamous Epithelial Tissue be found in the body? | The bladder or uterus |
| Name the 4 nucleotide bases of a DNA | thymine, cytosine, adenine and guanine |
| Describe the function of sebaceous glands. | Sebaceous glands lubricate skin by producing sebum; these glands develop on hair follicles in the dermis |
| What layer of skin are sebaceous glands found on? | The dermis, The 2nd layer of the skin |
| What is the DNA Compliment of this sequence? AGC-TGC-AGT | TCG-ACG-TCA |
| Transcribe this DNA sequence TCG-ACG-TCA (ConvertDNA to mRNA) | AGC-UGC-AGU |
| What are the Layers of the epidermis? Order from the outermost layer to the deepest. | Stratum corneum, Stratum lucidum, Stratum granulosum, Stratum spinosum, and Stratum basal |
| Stratum Corneum | Dead, flat, scale like keratinized cells, slough off. OUTTERMOST LAYER of the epidermis |
| Stratum Lucidum | Only palms, and soles of feet (cells look clear) |
| Stratum Granulosum | Keratinization process beings. Cells die |
| Stratum Spinosum | 8 to 10 cell layers thick Contains melanocytes and keratinocytes |
| Stratum Basal | Continuous cell division Deepest epidermal layer (INNERMOST LAYER) Mostly keratinocytes |
| Which layers of the Epidermis receives nourishment from the Dermis? | Stratum spinosum and Stratum basal |
