-
anatomy
branch of science that deals with the structure(morphology) of body parts-their forms and how they are organized.
-
physiology
concerns the functions of body parts-what they do and how they do it.
-
anatomical position
the body is standing erect, face forward, with the upper limbs at the sides and palms forward
-
superior
body part is above another part. (The thoracic cavity is superior to the abdominopelvic cavity.)
-
inferior
- body part is below another body part.
- (the neck is inferior to the head)
-
anterior
- towrd the front.
- (the eyes are anterior to the brain)
-
posterior
- toward the back.
- (the pharynx is posterior to the oral cavity)
-
medial
imaginary midline dividing the body into equal right and left halves. Body part is medial if it is closer to the midline than another part. (The nose is medial to the eyes)
-
Lateral
- toward the side, away from the imaginary midline.
- (The ears are lateral to the eyes0
-
Bilateral
- Paired structures, one of which is on each side.
- (the lungs are bilateral)
-
Ipsilateral
- structures on the same side.
- (the right lung and the right kidney are ipsilateral.)
-
contralateral
- structures on opposite side.
- ( A pt with a fractured bone in the right leg would have to bear weight on the contralateral-in this case-,left-lower limb.)
-
proximal
- body part that is closer to a point of attachment to the trunk than another body part.
- (The elbow is proximal to the wrist)
-
distal
- opposite of proximal. body part is farther from a point of attachment to the trunk than another body part is.
- (the fingers are distal to the wrist)
-
superficial
near the surface
-
deep
- more internal than superficial parts. ( the
- dermis is the deep layer of the skin)
-
viscera
the thoracic cavity and abdominopelvic cavity, organs within these two cavities
-
parietal pleura
the walls of the right and left thoracic compartments, which contain the lungs, are lined with a membrane
-
visceral pleura
membrane covers each lung
-
parietal
membrane attached to the wall of a cavity
-
visceral
membrane that is deeper-toward the interior- covers an internal organ such as a lung.
-
pleural cavity
potential space between parietal and visceral pleural membrane,(no space exists)
-
pericardial membranes
surrounds the heart
-
organ systems
integumentary system, skeletal system, muscular system, nervous system, endocrine system, cardiovascular system, lymphatic system, digestive system, respiratory system, urinary system, reproductive system
-
integumentary system
skin, hair, nails, sweat glands and sebaceous glands
-
skeletal system
bones, ligaments and cartilages that bind bones together.
-
muscular system
muscles provide forces that move body parts by contracting and pulling their ends closer together.
-
nervous system
brain, spinal cord, nerves and sense organs.
-
endocrine system
includes all the glands that secrete chemical messengers called hormones.
-
cardiovascular system
heart, arteries, veins, capillaries, and blood.
-
lymphatic system
- lymphatic vessels, lymph nodes, thymus, spleen, and a fluid called lymph.
- carries certain fatty substances away from the digestive organs.
-
digestive system
mouth, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancrease, small intestines, large intestines
-
respiratory system
nasal cavity, pharynx, larynx, trachea, bronchi, and lungs
-
urinary system
kidneys, ureters, urinary bladder, and urethra.
-
reproductive system (male)
scrotum, testes, epididymids, ductus deferentia, seminal vesicles,prostate gland, bulbourethral glands, peniss and urethra
-
reproductive system (female)
ovaries, uterine tubes, uterus, vagina, clitoris, and vulva.
-
abdominal cavity, organs
stomach, liver, spleen, gallbladder, kidneys and most of the small and large intestines
-
pelvic cavity organs
large intestine, urinary bladder, and internal reproductive organs.
-
oral cavity
teeth and tongue
-
nasal cavity
nose, right and left portions ofby a nasal septum
-
orbital cavities
eyes and skeletal muscles and nerves
-
middle ear cavities
middle ear bones
-
Requirements of organisms
water, foods, oxygen, heat, pressue
-
water
h2o, most abundant chemical in the body. transports substances within the organism and is important in regulating body temp.
-
foods
substances that provide the body w/ necessary chemicals.
-
oxygen
gas that makes up about 1/5 of ordinary air. it is used to release energy from food substances
-
-
pressure
force of something. (pressure is important in breathing)
-
homeostasis
stable internal environment
-
metabolism
the total sum of all of the chemical reactions in the body that break substances down and build them up.
-
level of organization
atom, molecule, macromolecule, organelle, cell, tissue, organ, organ system, organism
-
characteristics of life.
movement, responsiveness, growth, respiration, digestion, absorption, circulation, assimilation, excretion.
