The animal Body Flashcards
4 (5) levels of organization
cells tissues organs organ system organisms
number of organ systems and name them
11 skeletal muscular nervous reproductive urinary respiratory
digestive endocrine circulatory lymphatic integumentary and immune systems
fct of nervous and endocrine systems
communication and integration
fct muscular and skeletal
support and movement
fct digestve, circulatory, repsiratory, urinary
regulation and maintenance
fct integumentary and immune
body defense
body cavities contain what
internal organs
visceral organs
interbal organs partially or completely in a body cavity
2 main body cavities
dorsal and ventral cavity
2 ventral cavities (in embryonic dev only ventral cavity) and separated by what
thoracic cavity and abdominopelvic cavity
separated by diaphragm
thoracic cavity includes….
pericardial cavity
right pleural cavity
left pleural cavity
mediastinum (in middle contain heart, trachea…)
abdominpelvic cavity is separated in 2 cavities and state the organs they contain
abdominal cavity:
- stomach
- pancreas
- intestines
- kidneys
- ureters
- gallbladder
- liver
- spleen
Pelvic cavity
-bladder
-certian reproductive organs
part large inetstine
subdivisions dorsal body cavity
cranial cavity and spinal cavity
3 types of planes
sagittal, frontal, transverse
midsagittal
separates symmetrically right and left halves
tissue definiton and 4 primary tissues in vertebrates
group of cells with similar structure/fct
epithelial, connective, muscular, nervous
Epithelial tissue
plein de petits cube bine empile (1 range= simple, plusieurs range empile=stratified)
separated in
- simple: cuboidal (glands), squamous (lungs), columnar (repsiratory tract)
- stratified: squamous(where friction) , columnar (respiratory tract)
Connective tissue
separated in
- proper: loose or dense
- special: cartilage, bone, blood
proper loose tissue is strengthen by what and example of this tissue
adipose tissue, by collagen and elastin
subdivision of proper dense tissue
dense regular (tendons/ligaments) and dense irregular(packaging organs)
cells of special cartilage connective tissue
chondrocytes
component special blood connective tissue
erythrocytes (carries o2), leukocytes, plasma
cells of special blood connective tissue and what is canal adn system called
osteocytes
Canaliculi
Haversian system
Muscular tissue and say if volunatry contraction and if striated muscle
separated in
- cardiac (voluntary and striated) (ressemble plus en vague)
- smooth
- skeletal (voluntary and striated)
which type of muscular tissue contains actin and myosin filaments
skeletal
Nervous tissue
neuron
parts of neurons
cell body, axon, dendrites (receives info other neuronsP
bilateral symmetry
right and left is mirror image
4 main body regions
head, trunk, upper limbs, lower limbs
directional terms (6)
superior-inferior proximal-distal ventral-dorsal superficial-deep medial-lateral intermediate
