Lecture 1 (Unit 1 and 4) Flashcards
what is Anatomy
The form and structure of an organ (Ex cells layers)
What is Physiology
the function of a system (ex. how muscles function)
Metabolism
The sum of chemical reactions that occur in the body
anabolism
small molecules are joined to form larger molecules
Catabolism
large molecules are broken down into smaller molecules
tissues
groups of similar cells with similar functions
Epithiel tissue
covers exposed skin and lines the cavities
Connective tissue
connects, supports, binds structures and organs
Muscle tissue
Produces movement
Nerve tissue
Conducts nerve impulses for communication
Organs
a collection of tissues that structurally form a functional unit specialized to perform a function
Organ system
multiple relative organs that work together to coordinate activities and functions (ex digestive system)
Organism
something that has many related parts that function together as a whole
Anatomical position
a supine position upward with feet parallel flat on the floor, upper limbs at the side of the body, palms anterior facing the front, eyes forward
superior
closer to the head (ex the shoulders are superior to your knees)
Inferior
closer to the feet (ex your knees are inferior to your shoulders)
Anterior
Closer to the front of the body (ex your heart is anterior to your spine)
Posterior
Closer to the back (ex your spine is posterior to your heart)
Medial
Toward the midline (ex lungs are medial to the shoulder)
Lateral
Away from the midline (ex the shoulders are lateral to the lungs)
Proximal
Closer to the point of attachment (Ex The elbow is proximal to the hand)
Distal
Farther from the point of attachment (The wrist is distal to the elbow)
Superficial
Closer to the outside (The skin is superficial to muscles)
