Study Notes
Multiple Choice Questions
- Conserving heat: Regulation is the characteristic of life representing the body altering circulation near the skin to conserve heat when cold.
- Directional terms: Directional terms are used to label an image, such as superior/inferior, medial/lateral, proximal/distal, anterior/posterior, superficial/deep, cranial/caudal, dorsal/ventral, ipsilateral/contralateral.
- Negative feedback: When a variable is regulated by negative feedback, its value fluctuates above and below the set point, rather than being constant.
- Anatomy vs. Physiology: Anatomy focuses on structure (e.g., structure-focused labels), physiology on function (e.g., function-focused labels), and some concepts overlap both (e.g., overlapping concepts).
- Homeostasis example: Maintaining blood glucose levels by releasing insulin is an example of homeostasis.
- Homeostasis example: Maintaining body temperature by putting on a hoodie is an example of homeostasis.
- Homeostasis example: Maintaining body temperature by sweating is an example of homeostasis.
- Homeostasis example: Maintaining blood pH by hyperventilating is an example of homeostasis.
- Homeostasis response: Decreasing heart rate to lower blood pressure is a response to elevated blood pressure.
- Homeostasis response: Decreasing blood vessel diameter to increase blood pressure is a response to elevated blood pressure.
- Homeostasis response: Increasing blood vessel diameter to decrease blood pressure is a response to elevated blood pressure.
- Homeostasis response: The kidneys increase blood volume to increase blood pressure.
- Homeostatic response: The body opposes environmental changes to maintain homeostasis by negative feedback.
- Homeostasis response: The body does not do nothing; it will find a way to maintain homeostasis using negative feedback.
- Homeostasis response: Blood sugar levels increase after a meal, so the body lowers them using insulin, which is an example of negative feedback.
True or False Questions
- Skin sensory receptors: The skin contains sensory receptors in the epidermis and dermis.
- Blood pressure and feedback: When blood pressure is elevated, the body employs negative feedback loops to maintain homeostasis.
- Body temperature and feedback: When body temperature drops below normal, dermal blood vessels dilate.
- Skin pigmentation and melanocytes: Skin pigmentation differences are due to varying numbers of melanocytes within each individual.
- Body heat conservation: Vasodilation of dermal blood vessels results in loss of body heat.
- Body heat conservation: Vasoconstriction of dermal blood vessels results in conservation of body heat.
- Skin color and heredity: The amount of melanin in the skin is partially determined by heredity.
- Skin color pigments: Normal skin color results from a combination of hemoglobin, melanin, and carotene.
Fill-in-the-Blank Questions
- Skin pigment acquired from vegetables: Carotene is acquired from yellow-orange vegetables.
- Conversion of carotene: In the body, carotene is converted into vitamin A.
- Pigment produced by light exposure: The black or brown pigment produced in response to light exposure is melanin.
- Milk and earwax: Are secreted from modified sweat glands.
Matching Questions
- Lateral malleolus: The bony prominence on the outside of the ankle, formed by the distal end of the fibula.
- Medial malleolus: The bony prominence on the inside of the ankle, formed by the distal end of the tibia.
- Tibial tuberosity: A roughened area on the anterior surface of the tibia, just below the knee, where the patellar ligament attaches.
- Condyle: A rounded projection at the end of a bone, typically part of a joint, such as the tibial condyles that articulate with the femur.
Additional Questions
- Function of nails: Protecting distal tips of digits, assisting in grasping objects, and preventing damage or extensive distortion during physical activities are functions of nails.
- Sweat and cooling: Sweat cools the body through evaporation, convection, and radiation.
- Subcutaneous layer: The subcutaneous layer is part of the integument, consists of areolar and adipose connective tissue, and serves as thermal insulation.
- Lines of cleavage: Lines of cleavage indicate the predominant orientation of collagen fibers in the skin. Incisions parallel to cleavage lines heal faster than those perpendicular to them.
