line in the oral cavity and are shed from the surface. bacteria are often seen on these cells

tight junction where cardiac muscle cells branch and join with one another end to end 

allows for the communication of information from one cell to another

a specialized blood-producing tissue found in the cancellous bone

the outter layer of long bone tubes

the inner layer of bone, which is spongy

consists primarily of fat cells, gradually replaces red marrow in some bones as the skeleton matures

part of the body's defense mechanism

anaerobic bacteria that are found in dental cavities and other holes

outtermost layer of the heart

double-layered sac that holds the heart in the center of the chest without hampering its movements

1) Pericardium

2) Myocardium

3) Endocardium

middle layer of the heart

composed of cardiac muscle tissue and makes up the bulk of the heart

the thin innermost layer that lines the cavities of the heart

microscopic air sacks bundled at the ends of bronchioles

where gas exchange occurs in the lungs

largest organ of the human body

functions as a protective coating, and forms an effective barrier against disease causing microbes

how ribosomes attract the coded amino acids

process from sensory stimulus to nerve impulse

nerve cells that are the structural and functional unit of the nervous system

made up of the brain and the spinal cord

responsible for majority of the body's interpretative activities as it receives data from the major sensory organs of the body 

sysem that contains all other component structures

(not the brain or spinal cord) 

(sensory neurons)

convey information (provided by sensory receptor cells) to the central nervous system

(motor neurons)

composed of 2 subsets (somatic and autonomic nervous system)

usually glands or muscles

part of efferent system that controls our subconcious activities, such as digestion

divided into the sympathetic and parasympathetic divisions

portion of efferent system mainly composed of the cranial and spinal nerves and contros the voluntary activities of the body
