,Anatomy The study of body structure
Physiology the study of how the body and its parts work together to perform functions of life.
study of physiology centers on the body's tendency toward homeostasis.
Gross anatomy (macroscopic anatomy) Study of large structures, easily observable and no microscope needed.
Microscopic Anatomy (Histology) (Cytology) deals with structures too small to be seen with the naked eye and a microscope
is needed.
Histology- Study of tissues Ex: ( Connective tissue)
Cytology- Study of cells Ex: (Neurons)
Regional Anatomy Study of interrelationships of specific regions of the body such as the head or
chest and shows hows the muscles, nerves and blood vessels and other
structures work together in that region.
Systemic anatomy Is the study of the structures that make up a discrete body system—that is, a
group of structures that work together to perform a unique body function. For
example, a systemic anatomical study of the muscular system would consider all
of the skeletal muscles of the body.
Homeostasis A tendency to maintain a balanced or constant internal state of all living things;
the regulation of any aspect of body chemistry, such as blood glucose, around a
particular level
Neurophysiology Physiology of the nervous system ( Brain, Nerves, Spinal cord work together to
perform a function like movement, vision and thinking)
Molecular level- observing an electrochemical signal travels along nerves).
physiologist A biologist who deals with the functions and vital processes of living organisms
Name the six levels of organization of the human body Cells , Organelles, Tissues, Organ, Organ Systems, Organism.
Name the the fundamental levels of an organism form Sub anatomic particles, Atoms, Molecules, Organelles, Cells, Tissues, Organs,
smallest to largest. Organ Systems, Organism.
Cell Is the smallest independently functioning unit of a living organism.
* All living structures of human anatomy contain cells, and almost all functions of
human physiology are performed in cells or are initiated by cells. Even bacteria
have cells.
Organelle A tiny cell structure that carries out a specific function within the cell
Tissue Is a group of many similar cells (though sometimes composed of a few related
types) that work together to perform a specific function.
Organ Is an anatomically distinct structure of the body composed of two or more tissue
types.
*Each organ performs one or more specific physiological functions.
, Organ System group of organs that work together to perform a specific function.
Name the 11 organ systems 1. Integumentary
2. Skeletal
3. Muscular
4. Nervous
5. Endocrine
6. Cardiovascular
7. Lymphatic/Immune
8. Respiratory
9. Digestive
10. Urinary
11. Reproductive
Integumentary system Consists of the skin, mucous membranes, hair, and nails
Function: Protects body from external structures, Has many sensory receptors
and sweat glands
Circulatory system (aka cardiovascular system) This system works as the transportation highway for
the body. It consists of the heart, blood, and blood vessels. It transports
substances such as oxygen, carbon dioxide, and nutrients in the body and
equalizes body temperature in the body.
lympathic system The lymphatic system transports lymph (a fluid) using lymph vessels, lymph
nodes, lymph ducts, and various glands. The lymphatic system is key for
immunity, blood pressure regulation, digestion, AKA the drainage system of the
body, carrying excess fluid, proteins, fats, bacteria, and other substances away
from the cells and spaces between cells to be filtered, excreted, and recycled.
respiratory system A system of organs, functioning in the process of gas exchange between the
body and the environment, Removing co2 from the body and brings in oxygen It's
consisting especially of the nose, nasal passages, nasopharynx, larynx, trachea,
bronchi, and lungs.
Endocrine system The endocrine system includes all the glands that secrete hormones into the
bloodstream to regulate body processes. ( Pancreas, Pituitary glands)
Digestive System esophagus, stomach, and intestines and Liver are all part of the gastrointestinal
system as well as the Vagus Nerve which helps slow down bodily processes. The
system also removes waste and effects metabolism.
Urinary system kidneys, ureters, urinary bladder, urethra. These organs work together to filter
blood and remove toxins and waste from body tissues. The removal of excess
fluid through the urinary system also helps to regulate blood pressure and keep a
water balance.
Muscular System Consists of skeletal muscles, tendons that connect muscles to bones, and
ligaments that attach bones together to form joint
3 Types: striated (skeletal or voluntary), smooth (visceral or involuntary) and
cardiac (heart muscle)
- Enables Movement with the help of bones and joints
- Helps maintain body temperature.
Skeletal system Gives our bodies structure and protects major organs like the heart, lungs, and
brain,
- Enables movement with muscles
- Made up of bones and joints and cartilage
Nervous System Includes the brain and spinal cord, plus all the nerves that are connected to both
of these organs.
Specialized sensory nerves ( proprioceptors / Muscles spindles and GTO )
CNS - Brain and Spinal Cord
PNS - Ganglia and nerve endings
