2025–2026 – Complete Practice
Questions and Detailed Answers
Tissue - Correct Answer-Group of cells that work together
to perform specific functions
4 tissue types & function - Correct Answer-Epithelial:
cover, line, and protect the body and its internal organs
Connective: the framework of the body, providing support
and structure for the organs.
Nerve: composed of neurons and connective tissue cells
that are referred to as neuroglia
Muscle: has the ability to contract or shorten. It is
classified as voluntary muscle (skeletal muscles) or
involuntary muscle (smooth muscle and cardiac muscle)

Explain Mitosis - Correct Answer-Essential for growth and
repair. In this process DNA is duplicated and distributed
evenly to two caught cells
Explain Meiosis - Correct Answer-The special cell division
that takes place in the gonads, that is, the ovaries and
testes. In the process of meiosis, the chromosome number
is reduced from 46 to 23, so when the egg and sperm
unite in fertilization the zygote will have the correct
number of chromosomes.
Functions of the Skeletal system (7) - Correct Answer-1.
Support
2. Movement
3. Blood cell formation (hemopoiesis)
4. Protection of internal organs
5. Detoxification (removal of poisons)
6. Provision for muscle attachment
7. Mineral storage (particularly Ca2+ and phosphorus)

The body framework consists of (4) - Correct Answer-1.
Bone
2. Cartilage
3. Ligaments
4. Joints
Individual bones are classified by shape: 5 - Correct
Answer-1. Long bones
2. Short bones
3. Flat bones
4. Irregular bones
5. Sesamoid bones
Osteoblasts - Correct Answer-Cells that form compact
bone. When they become fixed in the dense bone matrix,
they stop dividing but continue to maintain bone tissue as
osteocytes

Axial Skeleton - Correct Answer-Consists of the 28 bones
of the skull, which are then separated into: 14 facial bones
and 14 bones of the cranium, 33 bones of the vertebral
column, Bones of the thorax, the sternum, and 12 pairs of
ribs
Axial Skeleton: 14 Facial bones - Correct Answer-2 Nasal
bones
2 Maxillary bones
2 zygomatic bones
1 mandible (only movable bone of the skull)
2 palatine bones
1 vomer
2 lacrimal bones
2 inferior nasal conchae
Axial Skeleton: 14 Cranial bones - Correct Answer-1.
Occipital
2. Frontal
