Module 8 pre-class HW

Superior sagittal sinus

A venous sinus located in the midline just dorsal to the corpus callosum, between the two cerebral hemispheres.

Cerebrum

Area of the brain responsible for all voluntary activities of the body

When our esophagus contracts involuntarily to move a bolus of food down, it is acting based on which subdivision of the motor nervous system?

Autonomic

Lateral sulcus

Separates temporal lobe from parietal and frontal lobes

Which division of the diencephalon acts as an information filter for sensory information that is forwarded to the cerebrum?

Thalamus

T or F Ganglia are clusters of neuron cell bodies located within the CNS.

While ganglia are clusters of neuron bodies, they are not in the CNS, but in the PNS.

Corpus callosum

a broad band of nerve fibers joining the two hemispheres of the brain.

Lateral ventricle

a complex C-shaped lateral portion of the ventricular system within each hemisphere of the brain

The location of conscious thought processes and the origin of all complex intellectual functions is the

cerebrum.

Cauda equina

collection of spinal nerves below the end of the spinal cord

identify the components of the brainstem.

midbrain, pons, medulla oblongata

Postcentral gyrus

primary somatosensory cortex (parietal lobe)

The ___________ nervous system transmits information from receptors to the CNS, while the ___________ nervous system transmits information from the CNS to the rest of the body.

sensory; motor

Cerebellum

the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance

Thalamus

the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
