serous fluid
A clear, watery fluid secreted by the cells of a serous membrane.
Muscular System
Consists of skeletal muscles, tendons that connect muscles to bones, and ligaments that attach bones together to form joint
integumentary system
Consists of the skin, mucous membranes, hair, and nail.
pelvic cavity
Contains urinary bladder, reproductive organs, and rectum
Pericardium
Double-layered membrane surrounding the heart.
Oligodendrocytes
Form myelin sheath in CNS
mediastinum cavity
Median space between the lungs
pleura
Membrane surrounding the lungs
peritoneum serous membrane
Membrane surrounding the organs in the abdomen. (Abdominal cavity)
skeletal system
Protects and supports body organs and provides a framework the muscles use to support movement. Made up of bones and joints
Schwann cells
Supporting cells of the peripheral nervous system responsible for the formation of myelin.
diapgragm
a dome-shaped muscle that separates the thoracic cavity from the abdominopelvic cavity
serous membrane
a thin membrane lining the closed cavities of the body
Superior means that a body part is
above another part or closer to the head
epi
above, upon
Neurilemma
additional external myelin sheath that is formed by Schwann cells and found only on axons in the peripheral nervous system
what is small molecules being joined to form large molecules a example of?
anabolism
Inferior means that a body part is
below another part or closer to the feet
what does the muscular system provide?
body movement and heat
what is large molecules being broken into smaller molecules?
catabolism
glial cells (glia)
cells in the nervous system that support, nourish, and protect neurons
the brain is in the
cranial cavity
the hand is what to the scapula? in directional terms
distal
Physiology is the study of body parts
function
Nodes of Ranvier
gaps in the myelin sheath
what region is directly below the umbilical region
hypogastric region
Ependymal cells (CNS)
line cavities of the brain and spinal cord, circulate cerebrospinal fluid
Astrocytes (CNS)
maintain blood-brain barrier; provide structural support; regulate ion, nutrient, and dissolved gas concentrations; absorb and recycle neurotransmitters; form scar tissue after injury
visceral
pertaining to the internal organs
Parietal
pertaining to the wall of a cavity

what region is to the side of the umbilical region?
the lumbar regions
nervous system
the network of nerve cells and fibers that transmits nerve impulses between parts of the body. controls body movements
axon
the neuron extension that passes messages through its branches to other neurons or to muscles or glands
Myelination
the process by which axons become coated with myelin, a fatty substance that speeds the transmission of nerve impulses from neuron to neuron
Dorsal
toward the back
microglial cells
type of neuroglial cell that phagocytizes bacterial cells and debris
what in the central point of the 4 quadrants of the abdomen
umbilical
