BIOS-251 Human Anatomy & Physiology Exam 2 –
BIOS-251, Human Anatomy & Physiology, Exam 2
Study Guide | Comprehensive Q&A Review Material
Introduction:
This document contains an extensive question-and-answer
style review for BIOS-251 Exam 2, covering core topics such as
cell biology, tissues, membranes, muscle tissue, and the
nervous system. It also includes detailed exam-focused
material on the brain, spinal cord, cranial nerves, autonomic
nervous system, cell division, transport mechanisms, and
epithelial and connective tissues. The structured Q&A format
makes it ideal for exam preparation, revision, and
reinforcement of key anatomy and physiology concepts.
Exam Questions and Answers:
Pons have nuclei: what are they related to? ----Correct
Answer---Sleep, respiration, and posture
What are the cerebral peduncles? ----Correct Answer---The
midbrain is made of these, which are two stalks that anchor
the cerebrum to the brainstem.
,What is the second largest brain area that has more than half
of the brain's neurons? ----Correct Answer---Cerebellum.
Function of the cerebellum? ----Correct Answer---Balance,
coordination, movement
What does the diencephalon include? ----Correct Answer---
thalamus and hypothalamus
Cell division in which the nucleus divides into nuclei
containing the same number of chromosomes ----Correct
Answer---Mitosis
The resting phase of mitosis. Cell grows, performs its normal
functions, and prepares for division; consists of G1, S, and G2
phases ----Correct Answer---Interphase
Cells that have left the cycle and cease dividing for a long time
(or permanently) ----Correct Answer---G Zero (G0) Phase
The first gap, or growth phase, of the cell cycle, consisting of
the portion of interphase before DNA synthesis begins. ----
Correct Answer---G1 Phase
,The synthesis phase of the cell cycle; the portion of interphase
during which DNA is replicated. ----Correct Answer---S Phase
The second gap, or growth phase, of the cell cycle, consisting
of the portion of interphase after DNA synthesis occurs.
Growth and preparation for mitosis ----Correct Answer---G2
Phase
First and longest phase of mitosis, during which the
chromosomes become visible and the centrioles separate and
take up positions on the opposite sides of the nucleus ----
Correct Answer---Prophase
Second phase of mitosis, during which the chromosomes line
up across the center of the cell ----Correct Answer---
Metaphase
The third phase of mitosis, during which the chromosome pairs
separate and move toward opposite poles ----Correct Answer--
-Anaphase
, The final phase of cell division, between anaphase and
interphase, in which the chromatids or chromosomes move to
opposite ends of the cell and two nuclei are formed. ----Correct
Answer---Telophase
Division of the cytoplasm during cell division ----Correct
Answer---Cytokinesis
Cell division that produces reproductive cells (gametes) in
sexually reproducing organisms ----Correct Answer---Meiosis
Compare and Contrast Mitosis and Meiosis ----Correct Answer-
--Mitosis produces two diploid (2n) somatic cells that are
genetically identical to each other and the original parent cell,
whereas meiosis produces four haploid (n) gametes that are
genetically unique from each other and the original parent
(germ) cell.
Number of Chromosomes in Humans... ----Correct Answer---46
Haploid Number of Chromosomes In Humans ----Correct
Answer---23
