Anatomy & Physiology Flashcards
Protoplasm
Cells of all living substances are composed of this. Colorless, jellylike substance in which food elements such as proteins, fats, carbs, mineral salts and water are present.
Nucleus
found in the center of the cell. Important for cell reproduction & metabolism
Cytoplasm
all the protoplasm of a cell except that found in the nucleus. Watery fluid contains material for cell growth, reproduction, and self-repair.
Cell Membrane
part of the cell that encloses the protoplasm and permits soluble substances to enter and leave
Anatomy
study of structures of the human body that can be seen with the naked eye, science of the structure of organisms
Physiology
study of functions and activities performed by the body structures
Histology
“microscopic anatomy” study of tiny structures found in living tissue
Cells
the basic unit of all living things
Mitosis
process of cell reproduction in human tissues that occurs when the cell divides into two identical cells called daughter cells
Metabolism
Chemical process that takes place in living organisms, cells are nourished and carry out their activities.
Anabolism
constructive metabolism, process of building up larger molecules from smaller ones.
Catabolism
phase of metabolism in which complex compounds within the cells are broken down into smaller ones. Releases energy stored by special molecules to be used in muscle contractions, body secretions, or heat production
Tissue
collection of similar cells that perform a particular function
Connective Tissue
supports, protects, and binds together other tissues. Examples: bone, cartilage, ligaments, tendons, fascia
Adipose Tissue
Fat, gives smoothness and contour to the body
Epithelial Tissue
protective covering on body surfaces. Examples: skin, mucous membranes, lining of the heart, digestive and respiratory organs, glands
Muscle Tissue
Contracts and moves the various parts of the body
Nerve Tissue
carries messages to and from the brain and controls and coordinates all bodily functions. Composed of neurons
Organs
structures composed of specialized tissues designed to perform specific functions in plans and animals
Skeletal System
forms the physical foundation of the body. Provides shape and form, supports, protects, allows movement, producing blood for the body, storing minerals like calcium. Protects internal structures and organs.
How many bones does the skeleton have
206
How are muscles connected to bones
tendons
How are bones connected to each other
ligaments
Bones of the skull - cranium
8 bones
How many bones does the face have
14 bones, maxilla (upper jaw), mandible (lower jaw)
Occipital
hindmost bone of the skull
Two Parietal Bones
form the sides and top of cranium
Frontal
Forehead bone
Temporal
sides to the ear region
Thorax
chest or pulmonary trunk consisting of sternum, ribs, thoracic vertebrae.
Ribs
12 pairs of bones forming wall of thorax
Scapula
shoulder blade
Sternum
breastbone
Humerus
uppermost and largest bone of the arm
Ulna
inner and larger bone of the forearm
Radius
smaller bone in the forearm
Carpus
wrist, 8 small bones
Metacarpus
palm, five long slender bones
Phalanges
digits, 14 bones of the fingers
Myology
study of nature, structure, function, and diseases of muscles
Muscular system
covers, shapes, and supports skeletal tissue. Contracts and moves the body. 630 muscles
Striated Muscles
also known as skeletal or voluntary, are attached to the bones and make up a large percentage of body mass and are controlled by the will.
Nonstriated Muscles
also known as involuntary, visceral, or smooth, function automatically without will
A muscles 3 parts
Origin, belly, insertion
Muscular tissue can be stimulated by
Massage, electrical therapy current, light rays, heat rays, moist heat, nerve impulses, chemicals
Muscles of the scalp
Epicranius, occipitalis, frontalis, epicranial aponeurosis
4 Types of Tissues
Connective, Epithelial, Muscle, Nerve
11 Major Systems in the Body
Skeletal, Muscular, Nervous, Circulatory, Lymphatic/immune, endocrine, digestive, excretory, respiratory, integumentary, reproductive
