Parts of the brain
100
This region of the brain is responsible for regulating body temp, appetite, sleep and pleasure.
What is the hypothalamus
100
The four main components of a feedback loop.
What is detector/receptor, stimulus, control centre, effector
100
The contact points between cells.
What is cell junctions
100
The charge separation
There are a few more negative ions on the inside of the plasma membrane than outside.
100
Responsible for language comprehension (part of the left hemisphere)
What is the Wernicke's area
200
This part of the brain receives sensory information (sensory cortex)
What is the parietal lobe
200
The component of the feedback loops that initiates a response.
What is the control centre
200
The non-cellular component within all tissues
What is extracellular matrix
200
Where does potassium want to go?
Potassium wants to leave the cell because it is in high concentration inside the cell. (moves down its concentration gradient)
200
Cushions and protects the brain. Extensions of the spinal cord.
What is the ventricles
300
The fold of dura mater in the longitudinal fissure, separating the cerebral hemispheres
What is falx cerebri
300
The component of the feedback loops that create a response to the change.
What is effector
300
The 4 functions of connective tissue
What is 1) binding and supporting 2) protection against infection 3) repair tissue damage 4) insulation
300
- 70mV, the cell is in what state?
What is resting membrane potential
300
Coordination and initiation of motor movements
What is the primary motor cortex
400
This part of the brain is involved in thinking, memory, voluntary motor movements and sensory perception.
What is cerebral cortex
400
The component of the feedback loops that detect a change
What is detector/receptor
400
The component of connective tissue that is flexible with high stretch and holds cells/tissues together
What is collagen
400
Short lived local changes that can be summed
What is graded potentials
400
Includes the amygdala, hippocampus, hypothalamus. This system is responsible for memory formation/storage, emotion/arousal and smell.
What is the limbic system
500
The system that includes the amygdala, hippocampus, fornix and mammilary bodies. Involved in emotions and memory.
What is the limbic system.
500
Definition of a positive feedback loop
Intensifies/strengthens the body's controlled conditions.
500
The 6 functions of the skin
What is 1) thermoregulation 2) blood reservoir 3) protection 4) cutaneous sensations 5) metabolism 6) excretion and absorption (minor role)
500
A message transmitted to the muscle cell and then all over the muscle cell to cause a contraction is a process of what?
What is neurotransmission
500
This structure connects the right and left hemispheres and allows info to pass between them.
What is corpus callosum
