1. __________ lymphatic
vessels transport lymph to a lymph node, whereas __________ lymphatic vessels
carry lymph away from a lymph node.
Afferent; efferent
2. In the spinal cord,
the grey matter is __________ to the white matter.
Deep
3. Dissection Video Activity: Sheep Brain
a. which of the following ventricles is found under the
corpus callosum?
Lateral ventricles
**The lateral ventricles
lie side by side under the corpus callosum, separated by the septum pellucidum.
b.
which passageway connects the third and fourth ventricles?
Cerebral aqueduct
** The
cerebral aqueduct is the narrow passageway that connects the third and fourth
ventricles. It can sometimes be observed on a midsagittal section.
c. Identify the passageway found in the spinal cord that
is continuous with the ventricles.
Central canal
** The central canal is the canal found in the spinal
cord that originates off of the fourth ventricle.
d. Cerebrospinal fluid is produced within the ventricles.
True
** The choroid plexus produces cerebrospinal fluid. It
is found in each of the ventricles.
e. The ventricles are all interconnected.
True
** Narrow passageways connect the ventricles together,
so that cerebrospinal fluid flows freely inside the ventricular system.
4. The __________ are a
series of interconnected cavities that are filled with cerebrospinal fluid.
Ventricles
The ventricles of the
brain are a communicating network of cavities filled with cerebrospinal fluid
(CSF) and located within the brain parenchyma. The ventricular system is
composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct,
and the fourth ventricle
5. __________ contains
mostly myelinated nerve fibers, whereas __________ contains mostly unmyelinated
nerve fibers.
White matter;
gray matter
