Study Notes
Anatomical Position
- The anatomical position involves the subject standing erect, facing the observer with head level, eyes directed forward, and feet flat on the floor.
Body Orientation Terms
- Supine refers to the position of the body lying face up.
- Prone describes the position of the body lying face down.
- The feet being flat and directed forward relates to the anatomical position.
Directional Terms
- Distal describes a body part further away from the point of attachment.
- Anatomy focuses on the study of body structures.
- Physiology studies the functions of the body.
- Cadaver dissection was historically the primary method for studying anatomy.
Branches of Anatomy
- Microscopic anatomy focuses on structures that cannot be seen without a microscope.
- Homeostasis describes the maintenance of internal stability within the body.
Reference Points & Joints
- The body has specific reference points for locating structures, and freely movable joints containing synovial fluid are known as synovial joints.
Quadrants and Regions
- The right upper quadrant of the abdomen is located on the right side above the horizontal line drawn through the umbilicus.
- The anatomical region below the horizontal line through the umbilicus and on the left side is referred to as the left lower quadrant.
Homeostasis Components
- In the feedback control of homeostasis, receptors detect deviations from the set point.
- Homeostasis involves maintaining a stable internal environment.
Organ Systems
- The renal system regulates acid-base balance and manages water-electrolyte balance.
- The ovaries produce eggs in the female reproductive system.
Endocrine System
- A specific gland discussed may not belong to the endocrine system.
- The male reproductive system includes various organs except those not classified within it.
Learning Objectives & Homeostasis
- Understanding the body’s ability to maintain stable conditions pertains to learning about homeostasis.
- The main purpose of homeostasis is to regulate and maintain internal stability.
Anatomical Terminology
- Ventral refers to the front side of the body.
- Abdominal regions assist in describing locations in anatomical terms and facilitate medical practice.
- A transverse section divides the body into superior and inferior parts.
Serous Membranes
- The visceral layer of a serous membrane adheres to the viscera.
- Serous fluid functions to reduce friction between the layers of the membrane.
Life Processes
- Differentiation involves the transition of an unspecialized cell to a specialized state.
- The nervous system is responsible for detecting and responding to changes in the body.
Anatomical Regions
- The intercostal region is located between the thorax and pelvis.
- Hypertrophy refers to an increase in body size due to existing cell enlargement.
- Hyperplasia is the process of tissue growth involving new cell formation.
Positioning and Planes
- The opposite of the supine position is the prone position.
- The sagittal plane divides the body into left and right parts, with the midsagittal plane creating equal halves.
Body Cavities and Systems Coordination
- The iliac (inguinal) regions are located in the abdominal cavity.
- Homeostasis is coordinated primarily by the nervous and endocrine systems.
Anatomical Directions
- Dorsal refers to the back of the body.
