Lab 6. Vertebrate Design Flashcards
3 things all members of Infraphylum Vertebrata possess
- Neural crest cells
- Ectodermal Placodes
- Vertebrae surrounding nerve cord (axial support)
Some functions of integument (know as many as you can but not word for word)
- Protection from chemical injury, infection, desiccation
- Protection from mechanical injury
- Protection from predation
- Reception/transduction of stimuli
- Movement of materials for nutrition, excretion and respiration
- Body temp. regulation
- Locomotion
- Colouration for cryptic or display purposes
3 main layers of the skin
- Epidermis
- Dermis
- Hypodermis
What is dermis?
Layer of vascularized connective tissue beneath dermis
What is hypodermis?
When present, located between dermis and deeper tissues
3 main functions of cartilage and bone
- Muscle attachment
- Skeletal support
- Absorption and storage of mechanical energy during locomotion
3 types of vertebrate muscles
- Striated (skeletal)
- Smooth (involuntary)
- Cardiac (heart)
What is striated muscle?
Responsible for gross movement (locomotion)
What is smooth muscle?
Occurs in skin and lining of gut, blood vessels and reproductive tract
All animals are what in terms of food acquisition?
Heterotrophs (aka. must consume other organisms or their products to meet nutritional requirements)
Vertebrates all have what kind of circulatory system?
Closed
4 things included in vertebrate blood
- Plasma
- Erythrocytes
- Leucocytes
- Platelets
What is plasma?
Water and dissolved gasses, salts, nutrients and proteins
What are erythrocytes?
Transport O2 and CO2
What are leucocytes?
Function primarily in immunity
What are platelets?
Function in blood clotting
3 possible types of respiration
- Cutaneous
- Gills
- Lungs
Using 2 methods of breathing simultaneously
Bimodal breathing
Definition of excretion
Elimination of metabolic waste products from an animal’s body (we’re gonna focus on nitrogenous waste)
Definition of osmoregulation
Regulation of the balance of water and solutes
