TEST 2 - Dec 2019 Flashcards
- What are the 4 types of tissue? (4)
Epithelial tissue
Connective tissue
Muscle tissue
Nervous tissue
- What does epithelial tissue do? (2)
Secretes
Absorbs
( Covering + Lining / Mucous Secretion)
- What does connective tissue do? (2)
To support and connect tissue and organ
Protection
- What does muscle tissue do? (1 )
To form muscle to support the skeleton system and to generate forces.
However there are 3 different types of muscle tissue: Skeletal, Cardiac, and Smooth. They have different functions.
- What does nervous tissue do? (3)
They detect change from outside and organise exact response also sending signal out.
(Neurons: responsible for the sensory, integrative, and motor functions of the nervous system.
Glial cells: support the nervous tissue. )
- Does epithelial tissue have a high division rate? ( 1 )
Yes.
- What type of tissue are glands made up of? (1)
Epithelial tissue
- What are the 3 main components of Connective Tissue? (3)
Cells
Ground substance
Protein Fibres
- Which Connective Tissue cells secrete the fibres and ground substance? (1 )
Fibroblast
- What tissue type is blood? (1 )
Connective tissue
- What are the 3 types of muscle tissue? ( 3 )
Skeletal
Cardiac
Smooth
- Which of the 3 types of muscle are voluntary, and which are involuntary ? (3)
Voluntary: Skeletal
Involuntary: Smooth, Cardiac
- What is unusual about cardiac muscle? ( 1 )
Autorhythmicity: it’s able to initiate an electrical potential at a fixed rate that spreads rapidly from cell to cell to trigger the contractile mechanism.
- What are the 2 types of nervous tissue? (2 )
Neurones Glia cells ( neuroglia)
- What’s the difference between neurones and neuroglia? (2)
Neurones: the primary type of cell that most anyone associates with the nervous system. They are responsible for the sensory, integrative, and motor functions of the nervous system. (stimulated and respond)
Neuroglia: support cells, and many functions are directed at helping neurones complete their function for communication
- Where in the brain are most of the sensations of the body actually perceived? (1 )
Cortex (sensory)
- How many pair of spinal peripheral nerves (ie coming out of the spinal cord) are there? (1)
31
- How many cranial nerves are there? (1 )
12
- What are the two main FUNCTIONAL (ie referring to the kinds of ‘job’ they do) parts of the nervous system? (2)
Somatic
Autonomic
- What are the two main ‘GEOGRAPICAL’ (ie referring to where they are located in the body) parts of the somatic nervous system? (2)
Central and peripheral (CNS and PNS)
- Give one of other word could you could use for somatic Nervous system? (1 )
Voluntary
- …..and another world for autonomic (1 )
Involuntary
- Which part of the nervous system ‘deal with’ cardiac muscle, smooth muscle, glands and blood vessels ? (1 )
Autonomic
- Do somatic and autonomic neurones (nerve cells) sometimes travel in the same nerve? (1 )
Yes
- Why does the autonomic nervous system ‘want’ to maintain a constant internal environment? (2 )
Protein enzymes, body chemistry
- Do Some organs/tissues have both somatic and autonomic nerves attached to them - If so, give an example. ( 2 )
Yes
Diaphragm / Eyes
- Under what conditions is the parasympathetic NS dominant? (1 )
Unstressful
- Under what conditions is the sympathetic NS dominant? (1 )
Stressful
