Exam 4: Principles of Neural and Hormonal Communication

Most innervated blood vessels receive only sympathetic nerve fibres.

The primary olfactory cortex is on the temporal lobe.

Match the terms, labelled a. through c., with their descriptions. (Options may be used more than once or not at all.) a.timbre (quality) b.pitch (tone) c.intensity of a sound wave (loudness) -measured in decibels

Which of the following is a conscious interpretation of external stimuli?

Which of the following statements applies to fast pain?

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 -contains otoliths in gelatinous mass, movement of which bends hair cells

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 -predominates in fight-or-flight situations

What is the proper sequence of retinal processing?

The cortical gustatory area is located adjacent to the "tongue" region of the somatosensory cortex.

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 -lie entirely within the central nervous system

Pain may be elicited by thermal or chemical stimuli.

Light is a form of electromagnetic radiation composed of particle-like individual packets of energy called ____________________ that travel in wave-like fashion.

Match the terms, labelled a. through c., with their descriptions. (Options may be used more than once or not at all.) a.timbre (quality) b.pitch (tone) c.intensity of a sound wave (loudness) -dependent on the amplitude of the sound wave

The receptors for smell are located in the upper nasal cavity, out of the normal path of air currents.

Acetylcholinesterase is stored in secretory vesicles in the motor end plate of the muscle fibre.

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 -preganglionic fibres that release acetylcholine as their neurotransmitter

Colour blindness may be caused by vitamin A deficiency.

Parasympathetic preganglionic fibres arise from the __________________ and __________________ areas of the CNS.

Visual and hearing receptors are irreplaceable, but taste and olfactory receptors are continuously renewed.

The inner ear is involved only with hearing.
