Brady
Slow
Tachy
Rapid
Anatomical position
When you refer to right and left; this is the patient’s right and left
Supine
Lying on back facing up
Prone
Lying on stomach
Right lateral recumbent
Lying on right side (recovery postion)
Left lateral recumbent
Lying on left side (recovery position)
Medial
Toward the midline
Midline
Imaginary vertical line drawn through the center of the body dividing it into equal parts
Lateral
Away from the midline
Superior
Toward the head
Inferior
Toward the feet
Distal
Farther from the point of attachment
Proximal
Closer to the point of attachment
Anterior/ventral
Toward the front
Posterior/dorsal
Toward the back
Superficial
Toward the surface
Cranial cavity
Contains the brain
Thoracic cavity (chest)
Contains the heart, lungs, great vessels trachea, and esophagus
Abdominal cavity
Contain the stomach, intestines, liver, galbladder, pancreas, spleen, appendix, and kidneys.
Anatomy
Study of structure
Topographic anatomy
Looks at the external surfaces and the shapes given by underlying structures
Gross anatomy
Structures visible to the naked eye
Microscopic anatomy
Only visible through microscope
Physiology
The study of biological function
Homeostasis
Body’s state of balance between all the body processes
Ligaments
Structures that attach bone to bone
Cranium
Part of the skull containing the brain
Immovable joints
Bone joints that are fused together
Ex: parietal bones of the cranium
Slightly movable joints
Bones of these joints that have a limited range of motion
Ex: joints that make up the spinal column
Freely movable joints
Bones at these joints have a great range of motion
Voluntary muscle
Skeletal or striated muscle, is under voluntary control
Involuntary muscle
Is also called smooth muscle, not under conscious control
Cardiac muscle
Only found in the heart
Respiration
Refers to exchange of gases in the cells
Inspiration
Inhalation
Expiration
Exhalation
Pharynx
Throat
Larynx
The voice box
Trachea
The wind pipe
Bronchi
Part of the airway branching of the trachea
Alveoli
Structure at the end of the bronchioles where gas exchange occurs
Diaphragm
Major muscle of the respiratory system
Atria
Superior chambers of the heart
Ventricle
Inferior chambers of the heart
Coronary arteries
Arteries supplying the heart muscle with blood
Arteries
Carry blood away from the heart
E
As arteries become smaller they are called arterioles
Capillaries
are very thin blood vessels where the exchange of gases, nutrients, and wastes between the blood and cells occurs
Veins
Carry blood back to the heart
Venules are small veins that connect the capillaries to the veins
Central nervous system
Brain and spinal cord
Peripheral nervous system
Nerves that transmit impulses to and from the central nervous system
Somatic nervous system
Voluntary nervous system
Autonomic nervous system
Involuntary nervous system
Epidermis
Outermost layer of the skin
Dermis
Middle layer of the skin
Subcutaneous layer
Innermost layer of skin, mostly fat
Stomach
Organ in the digestive system where material is churned with digestive systems
Kidney
Organ of the urinary system that filters blood
Ureter
Tube that carries urine from kidney to the urinary bladder
Urinary bladder
Organ that stores urine
Urethra
Canal that carries urine from the urinary bladder out of the body
