anterior

front

ventral

front

visceral

memebrane that covers organs

umbilical

located around the navel or umbilicus

anatomical position

human standing erect, with face forward, arms at side, with palms forward

tissues

cells grouped together according to their similarity in shape, size, intercellular material, and function

transverse

horizontal or cross section cut dividing the body into upper and lower parts

adipose

tissue that stores fats / lipids, and acts as filler tissue: protects and cushions

anatomy

study ot the bodys parts

thoracic cavity

cavity that contains the heart and lungs

cartilage

white, semi-opaque, nonvascular connective tissue,w hich provides firm but flexible support

superior

above another

sagittal plane

plane that divides the body into left and right parts

superficial / external

near the surface, or on the outside of the body

coronal / frontal plane

plane where a vertical cut divides the body into anterior and posterior parts

caudal

tail end

cranial

skull or head end of the body

tendons

white glistening bands attaching skeletal muscle to the bones

deep

not on the surface, internal

cranial

cavity which contains the brain

connective tissue

tissue that supports and connects organs and tissues

distal

away from the point of attachment

serous

double -walled membrane that produces a watery fluid (serous) and lines clsoed body cavities

reproductive

system which reproduces human beings

dorsal

back or in back of

posterior

back or in back of

ligaments

strong flexible bands that hold bones together at the joints

pleural membrane

membrane that lines the thoracic or chest cavity and protects the lungs

epigastric

region located just below the sternum

integumentary system

system which regulates body temperature, eliminates waste, synthesizes Vitamin D, has receptors for temperature, pressure, adn pain

proximal

toward the point of attachment

epithelial tissue

tissue that protects by covering internal and external surfaces

membrane

two thin layers of tissue that covers a surface or divides an organ

urinary system

system which removes waste of metabolism from the body

skeletal system

system which gives shape to the body, protects, helps form blood, and stores minerals

physiology

study of the function of body parts

endocrine system

system that manufactures hormones

hypochondriac

region located on each side of teh epigastric region and below the ribs

Respiratory System

system that acquires oxygen and rids the body of carbon dioxide

planes

imaginary anatomical dividing lines

organelles

cell structures which help a cell to function

organs

tissues which form larger functioning and structural units

pelvic cavity

cavity which holds teh urinary bladder, reproductive organs, part of the large intestine and appendix

digestive system

system that prepares food for absorption and use by body cells through modification of physical and chemical stress

hypogastric

region located below the umbilicus (pubic area)

inferior

below another

organism

anything capable of carrying on life

iliac / inguinal

lowest region of the abdominopelvic cavity, located on each side of the hypogastric region

lumbar

left and right regions located on each side of teh umbilical region

medial

toward the midline

nervous system

system that communicates, controls, and coordinates body activity

parietal

outer part of the membrane that lines the cavity

muscular system

system that determines posture, produces heat, and provides movement

mucous membrane

membrane that lines surfaces and spaces that lead to the outside of the body, and produces mucous which lubricates and protects

dorsal cavity

cavity which contains the brain and spinal cord

organ system

group of organs that act together to perform a specific related function

spinal cavity

cavity which contains the spinal cord

peritoneal membrane

membrane that lines the abdominal cavity and protects the abdominal organs

section

cut made through the body in the direction of a certain plane

muscle tissue

type of tissue that contains cell material which has the ability to contract and move the body

pericardial membrane

membrane that lines the heart cavity and protects the heart

nervous tissue

tissue that contains cells that react to stimuli and conduct an impulse

Lateral

lying away from the median and sagittal plane of a body
