Question 1

How does epithelial tissue renew itself?

Accepted Answer

Epithelial tissue renews itself primarily through the mitosis of basal cells, which are located at the bottom layer of the epithelium. These cells divide and push new cells upwards to replace the older surface cells.

Question 2

Impulses conducted from the periphery of the body (e.g. ,muscles,glands)to the central nervous system (CNS)are conducted through which system?

Accepted Answer

Afferent pathways are responsible for transmitting sensory signals from the periphery of the body to the central nervous system (CNS), allowing the brain to receive and process information from the external and internal environment.

Question 3

The spinal cord consists of how many segments?

Accepted Answer

The spinal cord is divided into 31 segments, each giving rise to a pair of spinal nerves.

Question 4

Buccal mucosa renews itself in ____ days.

Accepted Answer

The answer of Buccal mucosa renews itself in ____ days.
...

Question 5

Which cell supports the nervous system?

Accepted Answer

Neuroglia, also known as glial cells, are the supportive cells in the nervous system that provide support and protection for neurons, unlike neurons, which are the primary signaling cells.

Question 6

Internal organs (viscera)receive most of their neural impulses from which nervous system?

Accepted Answer

The autonomic nervous system is responsible for regulating the functions of our internal organs (viscera), such as the heart, stomach, and intestines. It operates unconsciously and controls bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.

Question 7

Simple squamous epithelium functions as a lining in which location?

Accepted Answer

Simple squamous epithelium functions as a lining in the kidney, where it forms part of the filtration barrier in nephrons, allowing for the exchange of substances between blood and the urinary filtrate.

Question 8

The absorption of nutrients occurs in which location?

Accepted Answer

The answer of The absorption of nutrients occurs in which...

Question 9

The junctional epithelium of gingiva is replenished every _____ days.

Accepted Answer

The answer of The junctional epithelium of gingiva is replenished...

Question 10

Which body system relies on neural stimuli to function?

Accepted Answer

The endocrine system relies on neural stimuli to function, as the nervous system can trigger hormone release from endocrine glands.

Question 11

Connective tissue proper is classified as ______________.

Accepted Answer

Connective tissue proper is classified as dense, loose, or loose with special properties, reflecting the variations in the arrangement and density of the fibers and cells within the tissue.

Question 12

Which term represents a single layer of cells?

Accepted Answer

Simple epithelium refers to a single layer of cells, in contrast to stratified epithelium, which consists of multiple layers. Cuboidal and columnar describe the shape of cells rather than the number of layers.

Question 13

Impulses pass from the CNS to involuntary muscles via the _____ system.

Accepted Answer

Impulses pass from the Central Nervous System (CNS) to involuntary muscles and glands via the autonomic nervous system, which operates without conscious control.

Question 14

All body sensations are relayed to the ______ and the _______.

Accepted Answer

All body sensations are relayed to the brain, where they are processed, and the spinal cord, which acts as a conduit for signals between the body and the brain.

Question 15

Which epithelium consists of several layers,with only the basal cell layer in contact with the basal lamina?

Accepted Answer

Stratified epithelium consists of several layers of cells, but only the basal layer of cells is in contact with the basal lamina. This structure provides a protective function, allowing the epithelium to withstand wear and tear.

Question 16

What are the three types of muscle tissue?

Accepted Answer

Cardiac, skeletal, and smooth are the three types of muscle tissue. Cardiac muscle is found in the heart, skeletal muscle is attached to bones for movement, and smooth muscle is found in walls of organs.

Question 17

Each is part of a neuron EXCEPT one.Which is the EXCEPTION?

Accepted Answer

Plasma is not a part of a neuron. Neurons consist of axons, dendrites, and the cell body (perikaryon), among other structures, but plasma refers to the liquid component of blood, not a component of neurons.

Question 18

Ligaments and tendons are composed of which tissue?

Accepted Answer

Ligaments and tendons are both made up of connective tissue, which provides support and structure to the body by connecting different tissues and organs.

Question 19

Neuroglia cells are __________ numerous than neurons.

Accepted Answer

Neuroglia, or glial cells, are significantly more numerous than neurons in the human nervous system, providing support, protection, and nutrition to neurons.

Question 20

Which of the following insulates axons located outside the CNS?

Accepted Answer

The myelin sheath insulates axons located outside the central nervous system (CNS), allowing for faster transmission of electrical signals along the nerve fibers.
