Q

what is the human tissue act?

A
  • voluntary donation of bodies
  • requires dual signed consent by the donor and an immediate family member
  • most bodies are held for 18 months, however can be kept for longer period for teaching and research

Q

why does tissue have different physical properties and different structures of what they look like?

A

because the cell and extracellular material are different then we can classify things based on what is similar and different

Q

what does apical mean in terms of epithelial tissue?

A

the outer surface (microvilli)

17
Q

what does basolateral mean in terms of epithelial tissue?

A

the bottom surface

18
Q

what are the four functions of epithelial tissue?

A
  • provides physical protection
  • controls permeability
  • provide sensation
  • produce specialized secetions
19
Q

what is connective tissue?

A

connects parts of the body together

20
Q

how many different types of connective tissue and what are they called?

A
  • connective tissue proper
  • fluid connective tissue
  • supportive connective tissue
21
Q

how many types of connective tissue proper?

A
  • lose connective tissue proper
  • dense connective tissue proper
22
Q

how many types of fluid connective tissue?

A
  • blood
  • lymph
23
Q

how many types of supportive connective tissue?

A
  • cartilage
  • bone
24
Q

how many types of cartilage in supportive connective tissue?

A
  • hyaline cartilage
  • elastic cartilage
  • fibrocartilage
25
Q

what are the 6 functions of connective tissue?

A
  • a structural framework for the body
  • transport fluid and dissolved material
    protect delicate organs
  • support, surround, and interconnect other types of tissue
  • store energy in the form of triglycerides
  • defend the body from invading microorganisms
26
Q

what are the two important fibers?

A

collagen fiber: thicker and stronger
elastic fiber: stretchy

27
Q

fluid connective tissue contains?

A

immune cells to protect us

28
Q

what is connective tissue proper?

A
  • sheets and bands of tissue that are very strong and stretchy depending on the need
  • fill in space in the body
  • wrap around the body to protect organs
  • in the form of adipose storing energy as well
29
Q

how many different types of loose connective tissue proper?

A
  • areolar tissue
  • adipose tissue
  • reticular tissue
30
Q

how many different types of dense connective tissue proper?

A
  • dense regular
  • dense irregular
  • elastic
31
Q

what is connective tissue proper characterized by?

A
  • cells
  • two different fibers
  • structure
32
Q

how much muscle tissue makeup in our body?

A

50%

33
Q

how many types of muscle tissue?

A
  • skeletal muscle tissue
  • cardiac muscle tissue
  • smooth muscle tissue
34
Q

what is smooth muscle tissue?

A
  • lining the organs in our body (stomach)
35
Q

what is the key difference between these muscle tissue groups?

A

skeletal muscle tissue - volunteer control
cardiac+smooth muscle tissue - involuntary control

36
Q

what is the use of nervous tissue?

A

sending fast signals from one place to another (quick electric signals)

37
Q

what is the cell called in a nervous tissue?

A

neuron

38
Q

what are the cells supporting neurons called?

A

glia

39
Q

what does glia do?

A

support and look after the neurons

40
Q

what are the functions of neuroglia?

A
  • maintain physical structure of nervous tissue
  • repair nervous tissue after injury
  • perform phagocytosis
  • provide nutrients to neurons
  • regulate the makeup of the interstitial fluid surrounding the neurons
41
Q

in the nervous tissue ____ send electrical signals while ____ provide support

A

neurons;glia
