name the 6 branches of science
anatomy, physiology, histology, embryology, pathology, biology
anatomy
the study of the structure of the body and the relationship of the parts
physiology
the study of the normal functions and activities of organisms
histology
the study of the structure, composition, and function of normal cells and tissues
embryology
the study of the origin and development of an organism. From conception to birth.
pathology
the study the changes to normal structure and function of living things caused by disease
nucleus
spherical, centrally located "brain" of the cell.
nuclear membrane
encloses and protects the nucleus
cytoplasm
jelly-like substance containing fibers that support the cell
Golgi Apparatus
consists of small sacs, believed to manufacture carbohydrates and combine them with proteins
mitochondria
organelle with small sacs thought to provide the energy for the cell
lysosomes
sacs containing enzymes that digest molecules and particles for the cell.
endoplasmic reticulum
canals consisting of smooth and rough portions where the ribosomes containing RNA attach.
4 types of tissue
epithelial, connective, muscle, nerve
5 types of epithelial tissue
endothelium, mesothelium, simple, stratified, pseudostratified
endothelium
type of epithelial tissue that surrounds the heart, blood, and lymph vessels.
mesothelium
type of epithelial tissue that covers the surfaces of serous membranes.
simple epithelial tissue
type of epithelial tissue that has one layer of cells
stratified epithelial tissue
type of epithelial tissue that has three or more layers
pseudostratified epithelial tissue
type of epithelial tissue that has one layer but appears to have more.
7 types of connective tissue
bone, cartilage, dense fibrous, loose arieolar, reticular, adipose, hematopoietic
bone
type of connective tissue that is hard, unbendable, supports the body
reticular
webike connective tissue that supports the nerves and capilaries
loose, arieolar
type of connective tissue that is elastic and stretchable, connects adjacent body structures
dense fibrous tissue
type of connective tissue that is strong and bendable, found in tendons and ligaments
adipose
type of connective tissue that is fatty, pads and protects
cartilage
type of connective tissue that is firm and bendable
hematopoietic
type of connective tssue that produces blood, found in the bone marrow and lymphatic system
3 types of muscle tissue
skeletal, smooth, cardiac
skeletal muscle tissue
type of muscle tissue that is striated and voluntary
smooth muscle tissue
type of muscle tissue that is smooth and involuntary
cardiac muscle tissue
type of muscle tissue that is striated but involuntary
nervous tissue
composed of nerve cells, nerve fibers, and supporting tissue called neuralgia
9 body systems
skeletal, cardiovascular, respiratory, integumentary, urogenital, gastrointestinal, nervous, muscular, endocrine
skeletal system
body system that is the framework of the body, supports organs, attachment place for muscles
muscular system
body system that permits motion and movement.
cardiovascular system
body system that transports blood, includes the lymphatic system
respiratory system
body system that absorbs oxygen and removed carbon dioxide
integumentary system
body system that incudes the skin, hair, nails, sweat, sebaceous glands.
urogenital system
body system that provides for reproduction and urine excretion
nervous system
body system that processes stimuli and enabes the body to act and respond
endocrine system
body system that manufactures hormones
gastrointestinal system
body system that digests and absorbs food and excretes waste.
