Exam 4: Principles of Neural and Hormonal Communication

All postganglionic neurons bear __________________.

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.) a.sympathetic nervous system b.parasympathetic nervous system c.both sympathetic and parasympathetic nervous system d.neither sympathetic nor parasympathetic nervous system -innervates smooth muscle, cardiac muscle, and exocrine glands

Match the part of the autonomic nervous system, labelled a. through d., with its description(s). (Options may be used more than once or not at all.) a.sympathetic nervous system b.parasympathetic nervous system c.both sympathetic and parasympathetic nervous system d.neither sympathetic nor parasympathetic nervous system -preganglionic fibre that secretes acetylcholine

Match the divisions, labelled a. through d., with the anatomical and physiological autonomic features. (Options may be used more than once or not at all.) a.parasympathetic division b.sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -cause tear gland stimulation

Which association is NOT correct?

Match the divisions, labelled a. through d., with the anatomical and physiological autonomic features. (Options may be used more than once or not at all.) a.parasympathetic division b.sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -innervate the adrenal cortex

Describe how sensory adaptation occurs.

Which statement applies to the choroid?

What are the various roles of secondary messenger systems in sensory pathways?

Match the ear parts, labelled a. through e., with their characteristics. (Options may be used more than once or not at all.) a.external ear b.middle ear c.cochlea in the inner ear d.semicircular canal in the inner ear e.utricle and saccule in the inner ear -concerned with hearing

A photoreceptor generates action potentials when its photopigment is activated.

Match the receptors, labelled a. through c., to their locations. (Options may be used more than once or not at all.) a.chemoreceptors b.mechanoreceptors c.photoreceptors -otolith organs

Receptor potentials can be graded, with a stronger stimulus resulting in a larger receptor potential.

What are the three types of cones?

Match the divisions, labelled a. through d., with the anatomical and physiological autonomic features. (Options may be used more than once or not at all.) a.parasympathetic division b.sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -cause fat break down in adipose tissue

Light rays passing through a concave lens undergo convergence.

Which statement applies correctly to phasic receptors?

What happens when light passes from one medium to a medium of a different density?

Match the type of neuron, labelled a. through d., with its description(s). (Options may be used more than once or not at all.) a.all three types of neurons b.both afferent and efferent neurons c.afferent neurons d.efferent neurons or interneurons -carry information from the central nervous system

An EPP is similar to an EPSP, except that the magnitude of an EPSP is much larger.
