Anatomy Chapter 1 Anatomy terminology Flashcards
What is the lungs double membrane?
Pleura
What is the heart’s double membrane?
Pericardium
What is it called that covers the diagram and abdominal?
Peritonion
What are the levels of organization in order?
Chemical, Cellular, Tissues, Organ, Organ system and Organism
Chemical level purpose:
Chemicals come together to form cells
Cellular level purpose
The smallest unit of life
Tissues purpose
one cell type comes together to form a function
Organ purpose:
two or more tissue types
Organ system:
tissues together ex: liver
Organism
11 life processes
What are the 11 life processes
Metabolism
takes in molecules for energy, takes small ones to build up to large ones to build tissues
Responsiveness
change in environmental conditions and maintain homeostasis
Movement
move chemicals around, cells contract and move around
Growth
ability to grow, new cells
Differentiation
Ex: sperm ovulum come together to produce new
reproduction
must continue for life
Integumentary system
Hair, Skin, nails, fingernails, mammary glands, sweat glands, sebaceous glands, etc.
Skeletal system
Bones, joints, cartilage
Muscular system
Tendons, skeletal muscle, ligaments
Cardiovascular
Heart, vessels, artery, vein
Vessels bring blood
to the heart
Arteries bring blood
Away from heart
Lymphatic/Immunity
Thymus, Spleen, Thoracic duct, Red bone marrow, lymph nodes
Thymus purpose
above heart gland of maturation of t-cells
Spleen purpose
monitors blood for toxins
Thoracic duct
drains 3 quarters of body lymph
Red bone marrow
has blood cells
Lymph nodes
lymph nodes there monitor the composition of lymph
Central Nervous system
Brain, Spinal cord
Peripheral nervous system
Nerves, neurons outside
Function of Integumentary
protection, regulation of heat
support movement, storage of fat, blood cell production
Muscular function
movement, storage, heat
Cardiovascular function:
Transportation (waste, blood), protection against blood loss (blood clot), skin thermo regulate
Anatomical position
shoulder apart, chin up, etc.
Antecubital region
front of elbow
cubital region
back of elbow
Nervous system function:
sensory function, integrative, motor (what to do and giving command to do)
Endocrine function
regulate hormones, brain hypothalamus, pituitary gland, pineal gland, anterior-posterior, thyroid
Hypothalamus function
the base of the diencephalon controls the anterior pituitary
Anterior pituitary gland function
releases stimulation of thyroid hormone, a hormone that releases cortisol, human growth hormone
Pituitary gland function
below hypothalamus
Pineal gland function
secretes melatonin
Thyroid function
releases thyroid hormones
Lymphatic/immunity
Adrenal glands, pancreas, parathyroid glands
Lymphatic/Immunity function
fluid transport, immunity
