function of the body
physiology
the study of large body structures visible to the naked eye
gross or macroscopic anatomy
all the sturctures in a particuliar region of the body
regional anatomy
study of internal structures as they relate to the overlying skin surface
surface anatomy
traces structual changes that occur within the bosy thoughout the lifespan
developmental atanomy
developmental changes that occur before birth
embrylogy
what are the levels of organization
chemical (atoms,molecules,organelles)
cellular
tissue
organ
organ system
organismal level
To decribe the ability to maintain stable internal conditions
homeostasis
What are the three homeostactic control mechanisms
receptor
control center
effector
Is some type of sensor that monitors the environment ans responds to changes
receptor
determines the set point ,anayles the input it recieveds and then determines the apporiate response and course of action
control center
provides the means for the control centers response to the stimilus
effector
shuts off the original stimilus or reduces the intensity
negative feedback
examples of negative feedback
regulation of body temp
withdrawal reflex (hand jerked away from painfil stimilus)
control of blood glucose levels
homeostatic inbalance is
disease, illness
what are two divisions of the body
axial
appenducular
the axial part is made of
head ,trunk, neck
the appendicular part consit of
appendages or limbs that are attached to the axis
a vertical plane that devides the body into left and right parts
sagittal
lies exactly in the midline
median plane or midsaggital
other planes that offset the midline
parasagittal
lie vertically, divide the bosy into anterior and posterior parts
frontal or cornal
runs horizonally from right to left ,diving the body into superior and inferior parts
transverse or horizontal plane
a transverse section is called a
cross section
What are the two body cavities in the axial portion
dorsal and ventral
what are the two subdivions of the dorsal cavity
cranial
vertebral
what are the two subdivions of the ventral cavity
thoracic
abdominopelvic cavity
what is viserra
an organ in a body cavity
internal organs
the thoracic cavity is subdivided into
pleural cavities
mediastinum
the mediastium contains what cavity
pericardial (which encloses the heart)
this allows organs to slide without friction across cavity walls and one another as they carry out thier function
serous fluid
what are the five serous membranes
perietal pericardium
viseral pericardium
perietal pleura
viseral pluera
visceral peritoneum
lines the pericardial cavity
parietal pericardium
covers the heart within the cavity
viseral pericardium
lines the calls of the thoracic cavity
parietal pleura
covers the lungs
visceral pleura
associated with the walls of the adominopelvic cavity
parietal peritoneum
covers most organs within the cavity
visceral peritoneum
a thin double layered membrane
serosa or serous membrane
mebrand lining that covers the cavity wall
parietal serosa
parie -wall
