Study Notes
Digestive and Body Functions
- Functions of the digestive tract include breaking down food with enzymes, waste removal, and moving food via peristalsis; it does NOT perform gas exchange, which is the role of the respiratory system.
- Homeostasis is the process maintaining the stability of the body's internal environment amid internal and external changes.
Endocrine and Muscle Systems
- The endocrine system facilitates communication throughout the body using hormones.
- Anatomical position refers to the body facing forward in an anterior position.
- The largest organ in the human body is the skin.
Cellular and Tissue Functions
- Histologists study tissues, including the parenchyma of organs like the kidney.
- Erythropoiesis refers to the formation of red blood cells, while Hemopoiesis encompasses all blood cell formation.
- Keratin is a fibrous protein found in hair, skin, and nails, but not teeth.
Muscle Structure and Function
- Muscle cells contain myofibrils made up of sarcomeres, which are essential for contraction driven by filament sliding.
- The vastus lateralis is a leg muscle; injury may require mobility aids like a cane or crutches.
Nervous System and Reflexes
- The medulla oblongata controls vital functions, including heart rate and respiration.
- Simple reflexes are specific to the spinal cord and do not involve the brain.
Female Reproductive System
- Estrogen prepares the endometrium for potential pregnancy during the menstrual cycle.
Urinary and Excretory Systems
- Urine travels from the kidneys to the bladder via ureters.
- The gallbladder, which stores bile, is not essential for survival as the GI tract can produce bile without it.
Hormonal Functions in the Body
- Cortisol's roles include reducing inflammation and raising blood sugar, but it does not control motor impulses.
- Tropic hormones, like FSH, TSH, and LH, influence other endocrine glands.
Nutritional and Digestive Processes
- Mastication increases food surface area, aiding in digestion.
- Sperm are stored in the epididymis after production.
Respiratory Mechanics
- Inhalation involves diaphragm contraction, while external respiration refers to gas exchange in the alveoli.
Cardiac and Vascular Functions
- EKG deflections indicate the electrical activity before the heart contrasts and relaxes.
- White blood cells play a role in phagocytosis, essential for the immune response.
Skeletal and Muscular System Overview
- The axial skeleton includes 28 bones in the skull, and the vertebrae consist of cervical (7), thoracic (12), and lumbar (5) bones.
- Bones are categorized based on shape, including long, short, flat, or irregular types.
General Anatomy and Physiology
- The latissimus dorsi muscle is located in the shoulders.
- Villi are tiny projections in the duodenum and intestines that aid in nutrient absorption.
Miscellaneous Facts
- Normal urine production ranges from 1,500-2,000 ml daily.
- Non-respiratory air movements include yawning.
Additional Terminology
- Proximal refers to moving toward the body, whereas distal indicates moving away.
- An epiphysis is the end part of a long bone, specifically referring to the femur in the context of injury.
