1: Introduction Flashcards
The science of structure and the relationships among structures
Anatomy
The science of body functions, that is, how the body parts function
Physiology
What are the levels of study in Anatomy?
Gross Anatomy, Microscopic Anatomy/Histology, Neuroanatomy, Embryology
Describe Gross Anatomy (2)
- large structures
- easily observable
What level of study can only be views with a microscope due to its small structures?
Microscopic Anatomy/ Histology
Anatomy- Levels of Study
Normal gross and microscopic features and development of the nervous system. Aka Neural HSB
Neuroanatomy
Anatomy - Levels of Study
The original and development of the human body from fertilization of the ovum to extrauterine life. Aka Developmental HSB
Embryology
- forms the external body covering
- protects deeper tissue from injury
- synthesizes vitamin D
- location of cutaneous nerve receptors
Integumentary
- Protects and supports body organs
- provide muscle attachment for movement
- site of blood cell formation
- store minerals
Skeletal
- allows locomotion
- maintains posture
- produces heat
Muscular
- fast-acting control system
- responds to internal and external change
- activates muscles and glands
Nervous
- secretes regulatory hormones
- growth
- reproduction
- metabolism
Endocrine System
- transports materials in body via blood pumped by the heart
Cardiovascular System
- returns fluids to blood vessels
- disposes of debris
- involved in immunity
Lymphatic System
- keeps blood supplied with oxygen
- removes carbon dioxide
Respiratory System
- breaks down food
- allows for nutrients absorption into blood
- eliminates indigestion material
Digestive system
- eliminates nitrogenous wastes
- maintains acid-base balance
- regulation of materials (water, electrolytes)
Urinary system
Production of offspring
Reproductive system
Production of offspring
Reproductive system
Describe the anatomical position (4)
- standing erect
- head, eyes, toes directed forward
- heels and toes together flat on the ground
- upper limbs hanging by the sides with the palms facing forward
What are the 3 body planes and describe them
- Median: equal right and left
- Frontal/ Coronal: equal or unequal front and back
- Transverse: a horizontal plane that divides the body into upper (superior) and lower (inferior) section.
Superior vs. Inferior
Superior- toward the head
Inferior- away from the head or toward the lower part of the body
Anterior vs Posterior
Anterior: toward/ at the front of the body;
Posterior: toward/ at the backside of the body
Eg.
The breastbone is anterior to the spine (Ang breastbone ay nasa harap ng spine)
The heart is posterior to the breastbone (Ang heart ay nasa likod ng breastbone)
What’s the difference between medial, lateral, and intermediate?
Medial: toward/ at the midline of the body
Lateral: away from the midline of the body
Intermediate: between a more medial and a more Lateral structure
