How many steps are there in the scientific method?
4
Scientific Method Step #1
Examine natural events (or phenomena) through observation.
Scientific Method Step #3
Experiment and test the hypothesis through the collection of data.
Scientific Method Step #2
Develop a hypothesis (possible explanation) for explaining the phenomena.
Scientific Method Step #4
Determine if the data support the hypothesis, or if the hypothesis needs to be rejected or modified.
How is the scientific method used in the fields of anatomy and physiology today?
Today, we continue to use the scientific method for a variety of topics, such s to understand how the brain stores memories or explain how cancer may spread throughout the body.
How has the scientific method been used in the fields of anatomy and physiology?
Early anatomists and physiologists used the scientific method to explain how blood circulates through the body.
Histology
The study of body tissues.
Microscopic Anatomy
Examines structures that cannot be seen by the unaided eye.
What are the two subdivisions of microscopic anatomy?
Cytology and Histology
Cytology
The study of body cells and their internal structure.
Gross Anatomy
Investigates the structure and relationships of body parts that are visible to the unaided eye.
What are the subdivisions of Gross Anatomy?
Systemic Anatomy, Regional Anatomy, Surface Anatomy, Comparative Anatomy, and Embryology.
Systemic Anatomy
Studies the anatomy of each functional body system.
Regional Anatomy
Examines all of the structures in a particular region of the body as a complete unit.
Embryology
The discipline concerned with developmental changes occurring from conception to birth.
Surface Anatomy
Focuses on both superficial anatomic markings and the internal body structures that relate to the skin covering them.
Comparative Anatomy
Examines the similarities and differences in the anatomy of different species.
Neurophysiology
Examines how nerve impulses are propagated throughout the nervous system.
Name 5 sub disciplines of physiology.
Cardiovascular Physiology, Neurophysiology, Respiratory Physiology, Reproductive Physiology, and Pathophysiology.
Cardiovascular Physiology
Examines the functioning of the heart, blood vessels, and blood.
Respiratory Physiology
Studies how respiratory gases are transferred by gas exchange between the lungs and the blood vessels.
Reproductive Physiology
Explores how the regulation of reproductive hormones can drive the reproductive cycle and influence sex cell production and maturation.
Pathophysiology
Investigates the relationship between the functioning of an organ system and disease or injury to that organ system.
How are the studies of form and function interrelated?
The structure and form of a component of the body determine how it functions, meaning you must understand anatomy to understand physiology and visa versa.
What are the 6 best practices for studying anatomy and physiology?
Schedule regular daily study sessions well before the upcoming exam, Study for multiple short periods of time, Minimize your distractions, Utilize active learning methods wen you study, Study with a partner or group, Utilize all of the resources your textbook has to offer.
What is an example of an active learning method?
Make your own tables to organize material.
Active Learning
A process by which you are engaged in the material, problem solving, and applying what you have learned to previous knowledge.
Organization
All organism exhibit a complex structure and order.
Metabolism
The sum of all the chemical reactions that occur within the body.
What are the common characteristics among living things?
Organization, Metabolism, Growth & Development, Responsiveness, Regulation, and Reproduction.
Growth and Development
During their lifetime, organisms assimilate materials from their environment and often exhibit increased size (growth) and increased specialization as related to form and function (development).
What are the levels of organization within the body?
Chemical, Cellular, Tissue, Organ, Organ System, Organism.
Regulation
An organism must be able to adjust internal bodily function in response to environmental changes.
Reproduction
All organisms produce new cells for growth, maintenance, and repair.
Responsiveness
All organisms exhibit responsiveness, which is the ability to detect and react to stimuli (changes in the external or internal environment).
What is the integumentary system made up of?
The skin, associated glands, nails, and hair.
What is the function of the integumentary system?
Provides protection, prevents water loss and gain, synthesizes vitamin D, releases secretions, regulates body temperature, and houses sensory receptors.
What is the muscular system made up of?
The muscles.
What is the function of the skeletal system?
Provides support and protection, site of hematopoiesis (blood cell production), stores calcium and phosphorus, provides sites for ligament and muscle attachments.
What is the skeletal system made up of?
The bones.
What is the function of the muscular system?
Produces body movement, generates heat when muscles contract.
What is the function of the Nervous System?
Acts as a regulatory system that responds to sensory stimuli and controls muscles and some glands. Also responsible for consciousness, intelligence, and memory.
What is the function of the endocrine system?
Consists of glands and cell clusters that secrete hormones, (some of which regulate development, growth, and metabolism); maintain homeostasis of blood composition and volume, control digestive processes, and control reproductive functions.
What is the function of the urinary system?
Filters the blood to remove waste products and biologically active molecules, concentrates waste products in the form of urine and expels urine from the body.
What is the function of the respiratory system?
Responsible for exchange of gases (oxygen and carbon dioxide) between blood and the air in the lungs.
What is the function of the cardiovascular system?
Consist of the heart 9a pump) and blood vessels; the heart moves blood though blood vessels in order to distribute hormones, nutrients, gases, and pick up waste products.
Why is the anatomical position important in the study of anatomy?
Anatomists and physiologists describe body parts based on the premise that the body is in the anatomic position, which provides accuracy and clarity.
What is the function of the male reproductive system?
produces male sex cells (sperm) and male hormones (e.g., testosterone), transfers sperm to the female.
What is the function of the digestive system?
Mechanically and chemically digests food, absorbs nutrients, and expels waste products.
What is the function of the female reproductive system?
produces female sex cells (oocytes) and female hormones (e.g., estrogen and progesterone), receives sperm from male, site of fertilization of oocyte, site of growth and development of embryo and fetus, produces and secretes breast milk for nourishment of newborn.
Anatomic Position
An individual in the anatomic position stands upright with the feet parallel and flat on the floor, the upper limbs are at the sides of the body, and the palms face anteriorly; the head is level and the eyes look forward toward the observer.
