(50 cards)
What are the functions of skin?
protection, temperature regulation, synthesis of chemicals, sensation
step 6 of the scientific method
Form a conclusion- decide if hypothesis was roved/disproved
What is the subcutaneous layer of skin composed of?
areolar and adipose tissue
What layer of the epidermis is thicker in the palms of hands and soles of feet and sometimes completely missing in thin skin?
stratum lucidum
What is the most common type of cartilage found in the human body?
hyaline cartilage
What tissue type covers the epiphysis of long bones?
hyaline cartilage
pseudostratified columnar epithelium
single layer of columnar epithelium that appear stratified but at not because nuclei are at different layers; found in the respiratory tract and its function is to move mucus along
In the process of endochondral ossification, what type of tissue gives rise to future bones?
hyaline cartilage
Carcinoma
skin cancer; most common type; arises from epithelial cells
step 4 of the scientific method
Experiment/Collect data- perform an experiment and collect data
What are the 3 types of muscle tissue?
skeletal, cardiac, smooth
Where do accessory structures of the skin originate from?
epidermis
step 7 of the scientific method
Report- report findings; publish in journals
Adipose tissue
aka fat; protects and cushions; found beneath the skin, around the kidneys, and around the heart
Homeostasis
Maintaining a stable internal environment
What are the general types of connective tissue?
loose connective tissue, dense fibrous connective tissue, cartilage, blood
Superficial partial-thickness burn (1st degree burn)
affects only the epidermis; short healing time
Normal body temp
98.6 F
Histology
study of tissues
Rule of 9
divides the body into 9ths to determine plans to replace fluid and electrolytes and if skin grafts are required after a burn
Melanocytes
gives us our skin color; contains pigment called melanin
Osteoclasts
break down bone tissue
Step 1 of the scientific method
Make an observation/Ask a question- see something and want to know more about it
Full-thickness burn (3rd degree burn)
affects the dermis, epidermis, and accessory structures, and usually requires a skin graft
step 2 of the scientific method
Research- look up what is already know about it and see if your question is already answered
Short bones
cube like; roughly equal in width and shape
Long bones
longer than they are wide
step 3 of the scientific method
Form a hypothesis- identify independent and dependent variables and put into an "if...then..." statement
What are the functions of the skeletal system?
support, protection, points of attachment for muscles, storage o organic salts, and blood production
Melanoma
skin cancer; least common type; arises from melanocytes
What are the features of a synovial joint?
articular capsule, articular cartilage, synovial fluid, joint cavity
Axial skeleton
parts of the skeleton that compose the trunk of the body
Inflammation
the body's response to stress or injury; skin becomes red and warm to touch
Hypothermia
body temperature below normal
step 5 of the scientific method
Analyze data- organize data into charts and graphs
Cardiac muscle tissue
involuntary function; found in the heart
How are anatomy and physiology related?
form affects function
Anatomical position
standing erect, with hands to the side with palms facing out
Physiology
The study of the functions of the human body
Osteon
cylinder shaped, composed of osteocytes; surrounds a canal; found in compact bone
Keratinization
the hardening of kertinocytes
What feature in the dermis contributes to fingerprints?
dermal papillae
Negative feedback loop
An imbalance that is corrected by a response to restore balance
Skeletal muscle tissue
voluntary function; striated
What are the ways our bodies lose heat?
radiation, conduction, convection, and evaporation
Compact bone
tightly packed
Hypothalamus
body's thermostat
Anatomy
The study of the structure of the human body
Irregular bones
variety of shapes
What tissue type composes the epidermis?
stratified squamous epithelial tissue
