1
Q

conducts sensory impulses to the brain and motor impulses from the brain to the body; begins at the foramen magnum, ends at the conus medullaries in lumbar region; the spinal or nerve cord is located in the vertebral foramen.

A

Spinal Cord

2
Q

composed of the frontal, parietal, occipital, and temporal lobes; largest part of the brain in mammals

A

Cerebrum

3
Q

deal with agression, mood, foresight, motivation, and social judgment; lie between the frontal bones and the central sulcus, above the eye orbits

A

Frontal Lobes

4
Q

function in integration of sensory information w the exceptions of vision, hearing, and smell; lie between parietal bones and the central sulcus

A

Parietal Lobes

5
Q

functions to recieve and interpret visual signals; lies between occipital bone and the parieto-occipital sulcus.

A

Occipital Lobe

6
Q

functions in memory, vision, learning, hearing, and emotional behavior; lies between the temporal bone and the lateral sulcus

A

Temporal Lobe

7
Q

thick folds in the surface of the cerebrum; gyrus is singular form of gyri

A

Gyri

8
Q

shallow groves in the surface of the cerebrum; sulcus is singular form of sulci

A

Sulci

9
Q

this fissure is a deep groove seperating the cerebrum into right and left halves

A

Longitudinal Fissure

10
Q

longitudal fissure divides the cerebrum into the right and left…

A

cerebral hemisphere

11
Q

involved in the regulation of posture and balance, fine motor control of skeletal muscles, and repetitive movements; second largest part of the brain in mammals and largest part of the brain in birds

A

Cerebellum

12
Q

an endocrine gland directly attached to the hypothalamus; divided into anterior and posterior portions; anterior portion produces hormones which regulate other endocrine glands and directly affect target cells; posterior portion functions to store and release hormones produced by th ehypothalamus

A

Pituitary Gland

13
Q

functions to integrate all sensory information (except smell) from the body, and channels it into proper processing regions in the cerebrum

A

Thalamus

14
Q

major integration system between various organ systems and the nervous system; coordinates activities of both nervous and endocrine systems, and between voluntary and autonomic activities; attached directly to the pituitary gland

A

Hypothalamus

15
Q

processes olfactory information and contains centers for reflex movements involved in eating such as chewing, licking, and swallowing

A

mammillary body

16
Q

regulates the day/night cycle; secretes the hormone melatonin, which effects sleepiness

A

Pineal Body

17
Q

part of the brain that contains the nerve tracts and physically joins the two cerebral hemispheres

A

Corpus Callosum

18
Q

located above the pons and is the mallest part of the brain stem; the oculomotor, trochlear, and trigeminal cranial nerves originate in this area; also called mesencephalon

A

Midbrain

19
Q

works with the medulla to control respiration and helps regulate sleep; origin for trigeminal, abducens, facial, and vestibulochochlear cranial nerves; located above the medulla on brain stem

A

Pons

20
Q

contains nerve centers for the regulation of heart rate, blood vesse diameter, respiration, swallowing, vomiting, coughing, sneezing, and hiccoughing; at the base of the brain stem

A

Medulla Oblongata

21
Q

located on the bottom-center of the brain where the two optic nerves cross

A

Optic Chiasma

22
Q

are located just below the frontal lobes; function in the sense of smell

A

Olfactory Bulbs

23
Q

to the brain

A

Afren

24
Q

from the brain

A

Efren
