    Study Notes

    Anatomy and Physiology Study Notes

    • Specializing in Ankle and Foot Structures: Regional anatomy is the specialty that studies the structures of the ankle and foot.

    • Marathon Runner Physiology: An exercise physiologist studies how the body uses nutrients during physical activity like a marathon run.

    • Smallest Biological Unit: The cell is the smallest independently functioning unit of an organism.

    • Tissues and Organs: A collection of similar tissues working together is an organ. A group of organs working together forms a system.

    • Support and Movement: The skeletal and muscular systems are responsible for structural support and movement.

    • Metabolism: Metabolism is the sum of all chemical reactions in the organism.

    • Energy Storage: Adenosine triphosphate (ATP) stores energy for use by cells, releasing that energy as needed.

    • Cancer Cell Characteristics: Cancer cells lack differentiation, meaning they do not perform specialized functions of healthy cells.

    • Vital Resource: Oxygen is the most critical resource for human survival.

    • Nutrient Essentiality: All classes of nutrients are essential. Micronutrients, like vitamins and minerals, need to be continuously consumed. Macronutrients (carbs, lipids, proteins) aren't micro- but are also vital.

    • Body Response to Cold: When cold, the body shifts to conserve heat.

    • Nerve Cell Communication: Stomach distension (due to food) is relayed by nerve cells to a central control center.

    • Heat Regulation Mechanisms: Responding to heat, the body adjusts, possibly using sweat glands and slowing breathing, to lose heat. The use of positive feedback loops like regulation body heat does not use positive feedback but negative.

    • Positive Feedback Loops: Childbirth is an example of positive feedback loop. This is not an example of normal physiological process using positive feedback loop

    • Anatomical Position: The anatomical position is described as standing facing the observer with the arms at the sides and palms forward, with feet slightly apart..

    • Anatomical Planes: Dividing a fruit in half creates a sagittal plane or a longitudinal plane

    • Body Regions: The lumbar region is inferior to the umbilical region and superior to the gluteal region.

    • Cavities: The heart is in the mediastinum within the thoracic cavity. The cranial cavity is at the top and the posterior (dorsal) cavity covers the back of the body.

    • Nobel Prize Winner and X-Rays: Wilhelm Röntgen discovered X-rays and earned the first Nobel Prize for this.

    • Cancer Cell Nutrient Uptake Study: Positron Emission Tomography (PET) is the most suitable technique.

    • Safe Imaging During Pregnancy: Ultrasound is the safest imaging method for pregnancy.

    • MRI Disadvantages: MRI scans have high costs and require the patient to be confined in a metal tube to avoid distortions from magnetic fields, for an extended duration.
