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.
