Human Anatomy Flashcards
What is the Anatomical Position?
Arms by side, palms forward, by side, erect posture, feet together facing forward.
Four Structural Levels in Body?
Cells, Tissues, Organs, Systems
Anterior (ventral)
Toward Front
Posterior (dorsal)
Toward Back
Superior
Towards Head
Inferior
Away from Head
Medial
Toward Midline Of Body
Lateral
Away From Midline of Body
Proximal
Toward Attached End Of Limb; Origin of Structure; Midline of Body
Distal
Away Attached End of Limb; Origin of Structure; Midline of Body
Superficial
External : Close To or On Body Surface
Deep
Internal : Further Beneath Body Surface Than Superficial Structures
Cervical
Around the Neck
Thoracic
Between Neck and Abdomen (Chest -Thorax)
Lumbar
(at Back) Between Abdomen and Pelvis
Plantar
Soles of Feet
Dorsal
Top of Feet and Hands
Palmar
Anterior (Ventral) Of Hands
Sagittal Plane
Longitudinal Line - Dives Right/Left Body/Parts
Transverse Plane
Horizontal line - Superior/Inferior Sections
Frontal Plane
Longitudinal Line - Anterior/Posteror Sections
Muscular Tissue
Soft Tissue - Composes of Muscle
Nervous Tissue
Central Nervous System - Brain/Spinal Cord - Regulates and Controls Functions/Activities
Connective Tissue
Body Fluids (Fibres/Cells) - Connects, Supports, Separates Different Types of Tissues/Organs.
Organ
Two + Tissues Combining To Serve As Specialized Physiological Center for Body.
Eg. of Organ?
Stomach - Muscular Tissue - forming walls. Epithelial Tissue : Lines Body Cavities - To prepare ingested food for digestion.
Epithelial Tissue
Lines various body cavities
Cavity
Fluid filled space in multi-cellular organism
Eg. of Body System
Digestive System - Mouth, Esophagus, Stomach, Intestines
