Study Notes
Female Reproductive System
- Responsible for the production of oocytes (egg cells) and serves as the site for fertilization and fetal development.
- Produces milk for newborns and hormones that influence sexual functions and behaviors.
- Comprises the ovaries, uterine tubes, uterus, vagina, and mammary glands.
Male Reproductive System
- Generates and transfers sperm cells to the female and produces hormones influencing sexual behaviors.
- Consists of the testes, accessory structures, ducts, and penis.
Homeostasis
- Refers to the body’s ability to maintain stable internal conditions despite external changes.
- Set points represent normal values for various variables (e.g., body temperature) and can adjust depending on body activities.
Body Planes
- Sagittal Plane: Divides the body into left and right parts.
- Median Plane: A sagittal plane along the midline that divides the body into equal halves.
- Transverse Plane: Separates the body into superior (upper) and inferior (lower) parts.
- Frontal Plane: Divides the body into anterior (front) and posterior (back) parts.
Pericardium and Pericardial Cavity
- Visceral Pericardium: Covers the heart; Parietal Pericardium: Thick, fibrous layer; together these form the pericardial cavity that reduces friction during heart movement.
Peritoneum and Peritoneal Cavity
- Visceral Peritoneum: Covers and anchors the abdominal organs; Parietal Peritoneum: Lines the inner wall of the abdominopelvic cavity; the peritoneal cavity also reduces friction.
Pleura and Pleural Cavity
- Visceral Pleura: Covers the lungs; Parietal Pleura: Lines the thoracic wall; the pleural cavity reduces friction and adheres the lungs to the thoracic wall.
Cell Structure and Functions
- Organelles are specialized structures within cells that perform essential functions for maintaining life.
Movement Through Cell Membrane
- Passive Transport: No energy is required; substances move along concentration gradients.
- Diffusion: Movement from higher to lower concentration, e.g., oxygen entering cells and carbon dioxide exiting.
- Osmosis: The diffusion of water across a selectively permeable membrane impacted by solute concentration.
- Hypotonic Solution: Lower solute concentration leads to cell swelling and potential lysis.
Microvilli
- Extensions of the cell membrane that increase surface area, especially in cells involved in absorption.
Protein Synthesis and Genetic Control
- Characteristics of a cell depend on proteins produced.
- mRNA is created during transcription, exits the nucleus, and undergoes translation to form proteins.
- Translation: mRNA attaches to ribosomes where tRNA reads codons and delivers corresponding amino acids, forming polypeptides.
Structure of DNA
- DNA consists of nucleotides made up of a 5-carbon sugar, phosphate group, and nitrogenous base.
- Forms a double helix structure with specific pairing:
- Adenine (A) pairs with Thymine (T) in DNA, and Uracil (U) in RNA.
- Cytosine (C) pairs with Guanine (G).
