Tags & Description
Anatomy
the study of body structure
Physiology
examines how the body functions
What are the 2 major body cavities?
dorsal cavity (posterior aspect) ventral cavity
Positive feedback
the outcome amplifies the stimulus
Negative feedback
the outcome negates the stimulus
The main division of bones
axial and appendicular skeleton
Superior

Inferior

Body planes
transverse frontal sagittal
Transverse plane
horizontal
Frontal plane
aka coronal plane vertical plane divides body into anterior and posterior sections.
Sagittal
vertical line dividing the body into left and right sections.
The visceral pleura is the inner layer covering the
lungs
The study of developmental changes (from conception to birth) is known as
embryologic anatomy
Lateral vs. medial
lateral: away from midline medial: towards midline
Body membranes
thin sheet of tissues lining the body cavities
3 layers of meninges
dura mater arachnoid pia mater
3 serous membranes
pleura pericardium peritoneum
Visceral layer
covers external surface of organs
Parietal layer
lines internal surface of body wall
pleura
serous membrane lining lungs
Pericardium
two layered serous membrane associated with the heart
Peritoneum
two layered serous membrane lining the abdominopelvic cavity
Abdominopelvic cavity has how many compartments?
9
Abdominopelvic regions
umbilical region epigastric region hypogastric region right/ left hypochondriac regions right/ left lumbar right/ left iliac
The body's largest and heaviest organ
the skin
Proximal vs distal
proximal: towards trunk *proximity distal: away from trunk *distant
Proximal
nearest point of attachment to limb or structure
Contents of ventral cavity
thoracic cavity abdominal cavity pelvic cavity
Contents of dorsal cavity
the brain and the vertebral cavity that contains the spinal cord CNS
3 types of cartilage
hyaline cartilage elastic cartilage fibrocartilage
4 types of tissues
epithelial tissue nervous tissue muscle tissue connective tissue
3 categories of dense CT
dense regular CT dense irregular CT elastic CT
The skin's first line of defense is
epithelial tissue
Functions of epithelium
protection secretion absorption lining of cavities
Simple epithelium
single layer of cells with each cell in contact with the basement membrane
Epithelial tissue lines
cavities and surfaces of organs
When epithelium is lining the internal surface of blood vessels it is called
endothelium
At any entrance or exit in the body you can find
epithelial tissue
Diaphragm
separates the thoracic cavity from the abdominopelvic cavity
Prognosis of epithelial injury is
good because epithelium is highly regenerative and heals well.
Meninges cover the
dorsal cavity
Where can you find simple squamous epithelium?
inside blood vessels
Where can you find simple cuboidal epithelium?
kidneys, ovaries, some endocrine
Simple columnar epithelium lines
fallopian tubes, GI tract, respiratory tract, stomach, intestine
Simple ciliated columnar epithelium is found on
trachea and lining airway
Stratified squamous epithelium lines
mouth, esophagus, vagina, hands, feet, eye
Stratified cuboidal epithelium lines
salivary glands, sweat glands, mammary glands
Nonkeratinized stratified epithelium is found on
conjunctiva of the eye, external female genitalia, and some parts of the oral cavity
