MIXED Flashcards
6 functions of the skin
PROTECTS the underlying tissues against; chemical damage & entry of microbes
SENSATIONS; vibrations, tickling, pressure
EXCRETION; water, urea, CO2, ammonia
SYNTHESIS of vitamin D
BLOOD RESERVOIR; extensive network of blood vessels
REGULATION of body temperature
5 ways resident microbial flora prevent the establishment of pathogenic microorganisms from populating the skin
Lowers the pH of skin
Excrete chemicals with antibacterial activity
Stimulate immune responses to fight pathogens
Compete for space/nutrients
Occupy the skins adhesion sites
Homeostasis mechanism to lower body temperature
Hypothalamus sends a message to the capillaries and sweat glands. Capillaries will dilate ( vasodilation) so blood will flush to the skin to lose more heat. Sweat glands will sweat.
Homeostasis mechanism to raise body temperature
Hypothalamus sends a message that triggers muscles to shiver, capillaries will constrict ( vasoconstriction) skin will get goosebumps to retain heat
Joint types; Name the joint that has SMALL amount of movement .
( joint can be found between ribs, sternum & pubic symphysis)
Cartilaginous Joint
Joint types; Name the joint that has A LOT of movement.
( joint can be found in the jaw bone, shoulder joint)
Synovial Joint
Joint types; Name the joint that has ALMOST NO movement.
( joint can be found in the sutures)
Fibrous Joint
5 functions of the skeletal muscles
Producing body movements
Stabilizing body positions
Protection of internal organs
Support of internal organs
Generating heat
Thoracic cavity boundaries;
Superior-

Anterior- Sternum
Lateral- Rib Cage
Body Planes-
Superior & inferior parts-
Anterior & posterior parts-
Equal left & right parts-
Superior & inferior- Transverse
Anterior & posterior- Frontal/Coronal
Equal left & right- Midsagittal
Why viruses need to enter a living cell/host to replicate
viruses use the enzymes, chemical processes and machinery of the host cell. Making them “ Obligate Intracellular Parasites”
Fungi-
Terms used to describe-
Fungal infections affecting the SURFACE of the body vs fungal infections affecting INTERNAL body organs
SURFACE- superficial fungal mycoses
INTERNAL- systemic fungal mycoses
Ideal habitats for the growth of resident microflora
Mouth and intestines provide warmth, moist conditions and ample nutrients
Bacteriostatic definition
Suppresses the growth of bacteria
5 methods for preventing disease transmission
Sanitation
Hygiene practices
Immunization
Isolation
