Last-anatomical features of brain

Question 1

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.

Answer 1

Spinal Cord

Question 2

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

Answer 2

Cerebrum

Question 3

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

Answer 3

Frontal Lobes

Question 4

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

Answer 4

Parietal Lobes

Question 5

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

Answer 5

Occipital Lobe

Question 6

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

Answer 6

Temporal Lobe

Question 7

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

Answer 7

Gyri

Question 8

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

Answer 8

Sulci

Question 9

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

Answer 9

Longitudinal Fissure

Question 10

longitudal fissure divides the cerebrum into the right and left…

Answer 10

cerebral hemisphere

Question 11

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

Answer 11

Cerebellum

Question 12

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

Answer 12

Pituitary Gland

Question 13

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

Answer 13

Thalamus

Question 14

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

Answer 14

Hypothalamus

Question 15

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

Answer 15

mammillary body

Question 16

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

Answer 16

Pineal Body

Question 17

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

Answer 17

Corpus Callosum

Question 18

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

Answer 18

Midbrain

Question 19

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

Answer 19

Pons

Question 20

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

Answer 20

Medulla Oblongata

Question 21

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

Answer 21

Optic Chiasma

Question 22

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

Answer 22

Olfactory Bulbs

Question 23

to the brain

Answer 23

Afren

Question 24

from the brain

Answer 24

Efren
