Human Anatomy Flashcards
What are the 2 subdivisions of human anatomy?
- Macroscopic Anatomy
2. Microscopic Antatomy
What is anatomy?
The branch of biology concerned with the study of the structure of animals and their parts
What is macroscopic anatomy?
Visible to the naked eye
Gross anatomy
What is microscopic anatomy?
Use of optical instruments in the study of various structures
Cytology, histology
What are the three main approaches to studying anatomy?
- Regional Anatomy
- Systemic Anatomy
- Clinical Anatomy
What is regional anatomy?
- Study of the body’s structure by parts or segments
- Example: 1. head, neck, and trunk
2. Upper extremities
3. Lower extremities
What is Systematic Anatomy?
- Study of the body’s organ system that work together to carry out complex functions
- Example: Skeletal, muscular, urinary, respiratory, etc.
What is clinical anatomy?
-Study of the body’s structures and functions important to medicine, dentistry and allied health sciences.
What is homeostasis?
- To keep in balance
- The ability to maintain a relatively stable internal condition, even though the outside world is continuously changing
- The body is in homeostasis when it’s needs are adequately met and is functioning smoothly.
- Example: teeter totter
What is the order of homeostasis on the teeter totter?
Look at diagram on page 3 of notes
Starts at stimulus: Heat-Receptors Temperature Sensitive cells- control Center Thermoregulatory center in Brain- Effectors Sweat Glands- Stimulus: Cold- Receptors Temperature Sensitive cells- Control center Thermoregulatory center in Brain- Effectors Skeletal Muscles- back to the beginning at the stimulus
What are the 11 systems in Systematic Anatomy?
- Integumentary System
- Reproductive System
- Endocrine a System
- Nervous System
- Digestive System
- Urinary System
- Circulatory System
- Cardiovascular System
- Lymphatic System
- Respiratory System
- Skeletal System
- Articular System
- Muscular System
What are the two components in the Integumentary System?
- Epidermis
2. Dermis
What is the Epidermis component of the Integumentary System?
- It is the protective outer layer
- Regenerative and avascular
What is the Dermis component of the Integumentary System?
- Dense layer of interlacing collagen and elastic fibers
- Account for strength and toughness of skin
What are the 5 functions of the Integumentary System?
- Protection
- Containment
- Heat Regulation
- Sensation
- Synthesis and storage of Vitamin D
What is protection mean as a function of the integumentary system?
It protects internal organs from disease
What is containment mean as a function of the integumentary system?
Organs, water, to prevent fluid loss
What is heat regulation mean as a function of the integumentary system?
Evaporation, loose body temperature, ultraviolet radiation
What is sensation mean as a function of the integumentary system?
Pain receptors
What is synthesis and storage of vitamin D mean as a function of the integumentary system?
Decrease Vitamin D, lower energy
Within the Integumentary System there are three different degrees of burns what are they?
- 1st degree burn
- 2nd degree burn
- 3rd degree burn
What is a 1st degree burn?
- Superficial
- Damage to the epidermis
- Redness of skin, pain, swelling, and peeling
What is a 2nd degree burn?
- Partial-thickness
- Epidermis and superficial dermis are damaged with blistering
- Nerve endings damaged
- Slow healing (3 weeks to months)
What is a 3rd degree burn?
Look at picture on page 4 in notes to see graphics
- Full-thickness
- Entire thickness of skin damaged and sometimes underlying muscle
- Sensory nerve endings are destroyed
- Minor degree of healing can occur around edges; ulcerated portions require skin grafts
The reproductive system is studied in two systems, what are they?
- Females
2. Males
What is the study of the Female reproductive system?
-Gynecology
What are the primary sex organs in females (gonads) and what do they produce?
- Ovaries
- produce oocytes (eggs)
What are the accessory reproductive organs in females?
-Ducts, glands, and external genitalia
What does the female reproductive system secrete?
-Secrete steroid sex hormones
What are the hormones that the female reproductive system produces?
-Estrogen and Progesterone
What is the study of the Male reproductive system?
Andrology
