Lab 1 Flashcards
Quiz #1
Anatomy
The study of structure in the human body
Physiology
The study of function in the human body
Gross Anatomy (3 types)
Regional, Systemic, & Surface
Regional Gross Anatomy
All structures in one part of the body (such as the abdomen or leg)
Systemic Gross Anatomy
Gross anatomy of the body studied by system
Surface Gross Anatomy
Study of internal structures as they relate to the overlying skin
Microscopic Anatomy (2 types)
Cytology & Histology
Cytology
Study of cells
Histology
Study of tissues
Embryology
Study of developmental changes of the body before birth
Pathological Anatomy
Study of structural changes caused by disease
Radiographic Anatomy
Study of internal structures visualized by X-Ray
Molecular Biology
Study of anatomical structures at a sub-cellular level
Renal
Kidney function
Principle of Complementarity
Function always reflects structure
Levels of Structural Organization (6)
Chemical, Cellular, Tissue, Organ, Organ System, Organismal
Homeostasis
Ability to maintain a relatively stable internal environment in an ever-chaning outside world ( the internal environment of the body is in a dynamic state of equilibrium)
Anatomical Position (BFPT)
Body erect, Feet slightly apart, Palms facing forward, Thumbs point away from body
Superior
Above/Toward the head
Inferior
Below/Away from the head
Anterior
Toward the front
Posterior
Toward the back
Medial
Toward the midline
Lateral
Away from the midline
Intermediate
Between a more medial and lateral structure (armpits)
Distal
Farther from the origin
Distal
Farther from the origin
Superficial
Toward the body surface
Deep
Away from the body surface
Sagittal
Divides body into right and left
Frontal/Coronal
Divides body into anterior and posterior
Transverse/Horizontal
Divides body into superior and inferior
Body Cavaties
Dorsal cavity (protects nervous system, divided into cranial cavity, which is within the skill and encases the brain, and the vertebrral cavity, which runs within the vertebral column and encases the spinal cord), Ventral cavity (houses the internal organs, called viscera, divided into thoracic and abdominopelvic cavaties
Dorsal Cavity
Protects nervous system (is divided into cranial cavity, which is within the skull and encases the brain, and the vertebral cavity, which runs within the vertebral column and encases the spinal cord)
Cranial Cavity
Is within the skull and encases the brain
Vertebral Cavity
Runs within the vertebral colum and encases the spinal cord
Ventral Cavity
Houses the internal organs (viscera), is divided into thoracic and abdominopelvic cavities
Thoracic Cavity
Contains heart and lungs
Abdominal Cavity
Contains digestive viscera (internal organs)
Pelvic Cavity
Contains bladder, reproductive organs, and rectum
Thoracic Cavities Subdivisions (3)
Pleural cavities, mediastinum, pericardial cavity
Pleural cavities
each house a lung
Mediastinum
contains the pericardial cavity, and surrounds the remainining thoracic organs
Pericardial Cavity
encloses the heart
How are the abdominopelvic cavity and the thoracic cavity separated?
By the diaphragm
Ventral Vody Cavity Membranes (3)
Parietal serosa, visceral serosa, and serous fluid
Parietal serosa
lines internal body walls
Visceral Serosa
covers the internal organs (touching organs)
Serous Fluid
seperates the serosae
Abdominopelvic Regions (9)
Umbilical (middle), epigastric (top middle), hypogastric (bottom middle), iliac/inguinal (bottom right and left), lumbar (middle right and left), hypochondriac (top right and left)
Abdominopelvic Quadrants (4)
Right upper (RUQ), left upper (LUQ), right lower (RLQ), left lower (LLQ)
Ventral
Toward the front
Dorsal
Toward the back
