- Posterior Pituitary
- Spatial Summation
- Connective Tissue
- a The regulatory protein that blocks the myosin-binding sites on actin molecules
- b An extension of the hypothalamus composed of nervous tissue that secretes oxytocin and antidiuretic hormone made in the hypothalamus, temporary storage site for these hormones.
- c A phenomenon of neural integration in which the membrane potential of the post-synaptic cell is determined by the combined effect of EPSPs or IPSPs produced nearly simultaneously by different synapses.
- d Animal tissue that functions mainly to bind and support other tissues, having a sparse population of cells scattered through an extracellular matrix
- e A type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction
5 Multiple choice questions
- A longitudinal bundle in a muscle cell (fiber) that contains thin filaments of actin and regulatory proteins and thick filaments of myosin
- Tissue consisting of long muscle cells that can contract, either on its own or when stimulated by nerve impulses
- The potential that an excitable cell membrane must reach for an action potential to be initiated
- Gap in the myelin sheath of certain axons where an action potential may be generated. In saltatory conduction, an action potential is regenerated at each node, appearing to "jump" along the axon from node to node
- Tissue made up of neurons and supportive cells.
5 True/False questions
Hypothalamus → An organism that is warmed by heat generated by their own metabolism, Heat usually maintains a relatively stable body temperature higher than that of the external environment.
Striated → The junction where a neuron communicates with another neuron or other cell across a narrow gap via a neurotransmitter(chemical) or an electrical coupling.
Anterior Pituitary → A portion of the pituitary that develops from nonneural tissue, consists of endocrine cells that synthesize and secrete several tropic and non tropic hormones
Enteric Division → One of the three divisions of the autonomic nervous system; consists of networks of neurons in the digestive tract, pancreas, and gall bladder; normally regulated by the sympathetic and parasympathetic divisions of the autonomic nervous system. (secretions + peristalsis can function independently from parasympathetic and sympathetic but can also be affected by it)
Cephalization → An evolutionary trend toward the concentration of sensory equipment at the anterior end of the body.
