Intro to anatomy Flashcards
Science of structure and the relationships among structures
Anatomy
Science of body functions, that is, how’s the body parts function
Physiology
[Anatomy - Levels of Study]
- Large structures
- Easily observable
Gross Anatomy
[Anatomy - Levels of Study]
- Very small structures
- Can only be viewed with a microscope
Microscopic Anatomy/histology
[Anatomy - Levels of Study]
- Normal gross and microscopic features and development of the nervous system
Neuroanatomy (aka Neural HSB)
[Anatomy - Levels of Study]
- Origin and development of the human body from fertilization of the ovum to extra uterine life
Embryology (Developmental HSB)
Levels of Structural Organization?
- Chemical level (atoms, molecules)
- Cellular level
- Tissue level
- Organ level
- Organ system level
- Organismal level
[Organ system]
- forms the external body covering
- protects deeper tissue from injury
- synthesizes vitamin d
- location of cutaneous nerve receptors
Integumentary
[Organ system]
- protects and supports body organs
- provides muscle attachment for movement
- cite of blood cell formation
- stores minerals
Skeletal
[Organ system]
- allows locomotion
- maintains posture
- produces heat
Muscular
[Organ system]
- fast-acting control system
- responds to internal and external change
- activates muscles and glands
Nervous
[Organ system]
- secretes regulatory hormones
- growth
- reproduction
- metabolism
Endocrine
What is the “master gland”?
Pituitary gland
[Organ system]
- Transports materials in body via blood pumped by the heart
- oxygen
- carbon dioxide
- nutrients
- wastes
Cardiovascular
Red veins deliver what type of blood?
Oxygenated blood
Blue veins deliver what type of blood?
Deoxygenated blood
[Organ system]
- returns fluids to blood vessels
- disposes of debris
- involved in immunity
Lymphatic
[Organ system]
- Keeps blood supplied with oxygen
- removes carbon dioxide
Respiratory
[Organ system]
- breaks down food
- allows for nutrient absorption into blood
- eliminates indigestible material
Digestive
[Organ system]
- Eliminates nitrogenous wastes
- maintains acid - base balance
- regulation of materials
- water
- electrolytes
Urinary
[Organ system]
- Production of offspring
Reproductive
Special terminology is used to prevent misunderstanding
Language of anatomy
Anatomical position is when a person is?
- standing erect
- head, eyes, toes directed forward
- heels and toes together fat on the ground
- upper limbs hanging by the sides with the palms facing forward
[ anatomical planes and sections ] equal right and left, only one medial plane
Median or midsagittal plane
[ anatomical planes and sections ] unequal right and left
Sagittal
[ anatomical planes and sections ] equal or unequal front and back
Coronal or frontal plane
