Intro
What is Anatomy?
The study of the shape and structure of body parts and their relationships to one another
What is anatomical position?
used as a reference point to accurately describe body parts and position. The body is erect with feet parallel and arms hanging at the sides with palms facing forward.
What does the integumentary system do?
hair skin nails; protects against pathogens and regulates body temperature
What does responsiveness mean?
irritability- ability to sense changes and react to them
What two cavities make up the dorsal cavity ?
cranial and spinal cavity
What is macroscopic anatomy?
structures visible to the eye
Directional Terms: Medial
provide an example
toward or at the midline of the body; on the inner side of
The nose is medial to the cheekbones
The spine is medial to the scapula
Directional Terms: anterior
define and provide an example
toward or at the front of the body- the trachea is anterior to the spine
What is excretion?
Removal of wastes
what structure separates the thoracic from the abdominopelvic cavity?
Diaphragm
What does tissue consist of ?
It consists of similar cells that have a common function
Body planes: Frontal ( coronal)
divides the body into anterior and posterior
What does the respiratory system do?
lungs, bronchi, trachea; supplies the body with oxygen and releases CO2 ( carbon dioxide)
This necessary function refers to all chemical reactions- catabolism and anabolism
Metabolism
The abdominopelvic cavity contains what structures/ organs ? ( multiple answers)
digestive, urinary, reproductive
What does the nervous system do?
brain, spinal cord, nerves; integrates information , responds to stimuli and detects changes
sagittal
midsaggital: divides the body into EQUAL left and right sides
sagittal: divides the body into unequal right and left sides
( provides a side view image)
Directional Terms: Distal
provide an example
farther from the origin of the body part of point of attachment of a limb to the body trunk
the foot is distal to the ankle
True/ False: Homeostasis is the body’s ability to maintain an absolute non-changing stable internal conditions.
False
What structure separates the cranial cavity from the spinal cavity?
foramen magnum
What is the function of the endocrine system?
glands, hormones; controls activities such as growth, reproduction, homeostasis
Body Planes: Transverse ( cross section)
divides the body into superior and inferior parts
What is the function of the cardiovascular system?
heart, vessels and blood; transports nutrients, gases and waste throughout the body
Provide two examples of homeostasis
blood glucose regulation via glucagon and insulin secreted by the pancreas
- shivering to increase body temperature
- increase in HR to maintain cardiac output when blood pressure drops
Name the 9 abdominopelvic regions and 4 quadrants
regions: right and left hypochondriac and epigastric
right and left lumbar and umbilical
right and left iliac and hypogastric
quadrants:
right upper, left upper
right lower, left lower
