Tissues
1. Epithelial 2. Muscle 3. Connective 4. Nervous
What distinguishes the three types of muscle tissues?
Location, Structure, and Control
5 functions of the integumentary system
1. protection 2. temperature regulation 3. sensation 4. vitamin D production 5. excretion
1.What distinguishes the central nervous system from the peripheral nervous system?
2. List one type of cell that is found only in the central nervous system.
1. The CNS is the central processing unit, and the PNS transmits information between the CNS and the rest of the body.
2. interneuron
What is multiple sclerosis? How does it affect the nervous system?
1. a chronic autoimmune disease that affects the central nervous system. 2. immune system attacks and damages the myelin sheath
What is distinction between stratified and simple tissues?
Simple consists of one layer of cells. Stratified consist of multiple layers of cells.
Why are skeletal and cardia striated, but smooth is not?
Smooth Muscle's cells aren't as long and fibrous and each cell only has one nucleus.
What are the two major types of glands found in skin?
sebaceous glands and sweat glands
List four signs that a sympathetic response has been triggered.
1. Increased Heart rate + Blood Pressure 2. Rapid Breathing 3. Pupil Dilation 4. Inhibited Digestion
How do action potentials trigger neurotransmitter release?
causing voltage-gated calcium channels at the axon terminal to open
What benefit does stratified
epithelium offer over simple epithelium?
Stratified Epithelium offers protection against physical and chemical damage compared to simple epithelium
What is an organ system?
Organs with complimentary
functions
What criteria are used to establish the severity of a burn?
Level of depth. Did it go through epidermis, Dermis, or fat?
At rest, are the following substances at higher concentration inside or outside the
neuron? Sodium ions, calcium ions, chloride ions, large organic ions, potassium ions.
Outside : sodium ions, calcium ions, and chloride ions
Inside : large organic ions, potassium ion
What happens to neurotransmitters after they bind to the post-synaptic neuron?
open or close ion channels, changing the neuron's membrane potential, making it either more or less likely to fire an action potential
Where in the body would you expect to find transitional epithelium?
Kidneys (renal pelvis), ureters, bladder, proximal urethra
List the major organ systems of the body.
1. Integumentary 2.skeletal 3.muscular 4.nervous 5. endocrine 6.cardiovascular 7.lymphatic 8.respiratory 9.digestive 10.urinary 11.reproductive systems.
How are third degree burns treated?
removing dead skin and tissue from the burned area
What distinguishes a graded potential from an action potential?
graded potential has a variable amplitude and decays over distance, while an action potential is an "all-or-none" event with a fixed amplitude
What distinguishes leak channels, voltage gated channels, and ligand gated channels?
Leak channels are always open, voltage-gated channels open in response to changes in membrane potential, and ligand-gated channels open when a specific chemical binds to them
List and describe the major types of connective tissue.
1. Connective Tissue Proper 2. Cartilage 3. Bone 4. Blood
List eight major conditions, ailments, or diseases of the integumentary systems
1. acne 2. eczema 3. psoriasis 4. skin cancer 5.rosacea 6. shingles 7. hives 8.burns
How do axon diameter and myelination influence conduction velocity?
A larger axon diameter increases conduction velocity. Myelination influences conduction velocity by allowing for rapid action potentials through a process called saltatory conduction
