\_\_\_ = study of structure \_\_\_ = study of the function of the cells
Do they always work together?
Anatomy
Physiology
Yes
What are the 2 main body cavities?
- dorsal
* ventral
What are the cavities in the dorsal body cavity?
- cranial (brain)
* vertebral (spinal cord)
What are the cavities in the ventral body cavity?
- thoracic (heart and lungs)
- abdominal (digestive viscera)
- pelvic (bladder, reproductive organs, rectum)
What are the different fluid compartments?
- intracellular
* extracellular (= interstitial fluid + plasma)
What are the different internal systems that exchange with the environment ? (4)
- digestive
- respiratory
- circulatory
- excretory
What are the organ systems?
- digestive
- circulatory
- respiratory
- immune and lymphatic
- excretory
- endocrine
- reproductive
- nervous
- integumentary
- skeletal
- muscular
What are 4 different types of tissues in the body?
- epithelial
- connective
- muscle
- nervous
What tissue covers the outside of the body and lines organs and cavities?
Epithelial
What are the types of cell organisation of epithelial tissues?
- cuboidal
- simple columnar
- simple squamous
- pseudostratified
- stratified
What are 2 ways of classifying epithelial cells?
- shape : cuboidal, columnar, squamous
* arrangement : simple, stratified, pseudo-stratified
Different between stratified and pseudo stratified?
Pseudo stratified: simple layer, every single cell has a different shape. Not stratified.
Stratified: multiple layers (skin)
Particularity of epithelial cells
Are polarized
Which tissue has a role of binding and support?
Connective
6 major subtypes of connective tissue
- loose CT
- fibrous CT
- bone
- adipose tissue
- cartilage
- blood
Which tissue is responsible for nearly all types of body movement?
Muscle
What are the 3 types of muscle cells?
- skeletal
- cardiac
- smooth
Which tissue functions in the receipt, processing and transmission of information?
Nervous
What are nervous tissues made of?
- neurons
- glia
What are neurons made of?
- cell body with nucleus
- dendrites
- axon
What are glial cela useful for?
They assist neurons by providing insulation, nutrients, replenishment.
Signalling is done by 2 systems, what are they?
What is the response limited to?
What does the signal travel along?
- endocrine (hormones)
Limited to cells that have the receptor for the signals.
Signal travels everywhere via bloodstream. - nervous (neurons)
Limited to cells that connect by specialized junctions to an axon that transmits an impulse.
Signal travels along axon to a specific location.
