Sample Exam - Final Exam Flashcards
the ANS provides the chief nervous control in which of the following activities
digesting food
when a pregnant female lies on her back, the weight of the uterus and developing fetus can compress the inferior vena cava, resulting in
decrease venous return in the lower limbs, leading to varicose veins
which of the following about gray rami is false
they carry preganglionic neurons from the anterior rami to trunk ganglia
which of the following is true about gray rami
- contain only sympathetic nerve fibers
- carry impulses from sympathetic trunk ganglia to spinal nerves
- located at all levels of the vertebral column
- contain only unmyelinated axons
how long after ovulation does implantation of an embryo usually occur
1 week
which of the following does not accurately describe mammary gland structure
milk in lactiferous sinus passes through a lactiferous duct before reaching the nipple
True: milk in the lactiferous duct passes through the lactiferous sinus before reaching the nipple
which of the following most accurately describes the endocrine system function
it reaches more types of cells and organs than the nervous system
which of the following describe an endocrine gland that is also an exocrine gland
pancreas
the pelvic splanchnic nerve contains ___ axons
parasympathetic preganglionic
which endocrine organ is physically 4 separate organs
parathyroid
preganglionic neurons of the autonomic nervous system have their cell bodies in
lateral horns of spinal cord gray matter
somatic motor pathways are different from autonomic motor pathways because
somatic pathways utilize 1 motor neuron, autonomic require 2
postganglionic neurons of the parasympathetic nervous system have their cell bodies in
intramural ganglia
an embryo obtains most of its nutrition from
the endometrial cells and secretions
the hypophyseal portal system transports hormones from the ___ to the ___
hypothalamus; anterior pituitary
the puerperium
refers to the post-delivery recovery period
the sympathetic division of the ANS is characterized by
ganglia close to the CNS and distant from effector
short preganglionic fibers, long postganglionic fibers
the anterior ramus of a spinal nerve may carry axons of
somatic motor neurons
sympathetic postganglionic neurons
parasympathetic preganglionic neurons
mesoderm gives rise to
muscle, bone, cartilage
the outer layer of the blastocyst, which attaches to the uterine wall is the
trophoblast
the primary germ layer that forms the trunk muscles, heart, and skeleton is
mesoderm
the thoracic splanchnic nerves contain which kind of axons
preganglionic sympathetic
the collateral ganglia contain which kind of cell bodies
postganglionic sympathetic
which of the following is the best way to describe how the ANS is controlled
little control by cerebrum; major control by hypothalamus, amygdaloid body, spinal and peripheral reflexes
the white rami communicantes contain which kind of axons
preganglionic sympathetic
medullary chromaffin cells occur in the
adrenal gland
the anterior lobe of the pituitary is the same as the
adenohypophysis
