Unipolar neurons are found in ___________.
- A.
Brain
- B.
Spinal Chord
- C.
Embryonic nervous tissue
- D.
Adult nervous tissue
Correct Answer
C. Embryonic nervous tissueExplanation
Unipolar neurons are found in embryonic nervous tissue. Unipolar neurons are a type of neuron that have a single process extending from the cell body, which then branches into two distinct fibers. These neurons are typically found in the early stages of nervous system development, specifically during embryonic development. Once the nervous system matures, unipolar neurons are replaced by other types of neurons such as bipolar or multipolar neurons. Therefore, the correct answer is embryonic nervous tissue.Rate this question:

The sensory organs contain ___________.
- A.
Unipolar neuron
- B.
Bipolar neuron
- C.
Multipolar neuron
- D.
Medullated neuron
Correct Answer
B. Bipolar neuronExplanation
Bipolar neurons are a type of sensory neuron that have two processes extending from the cell body - one dendrite and one axon. These neurons are found in specialized sensory organs such as the retina of the eye, the olfactory epithelium in the nose, and the cochlea in the ear. The bipolar structure allows these neurons to transmit sensory information from the peripheral sensory receptors to the central nervous system.Rate this question:

The part of the brain which controls emotional reactions in our body is ____.
- A.
Cerebellum
- B.
Cerebrum
- C.
Thalamus
- D.
Hypothalamus
Correct Answer
D. HypothalamusExplanation
The hypothalamus is responsible for controlling emotional reactions in our body. It plays a crucial role in regulating emotions, such as fear, pleasure, anger, and sadness. It receives information from various parts of the brain and body, and then releases hormones that influence our emotional state. Additionally, the hypothalamus is involved in the regulation of various physiological processes, including body temperature, hunger, thirst, and sleep, which can also impact our emotional well-being.Rate this question:

One of the following is the part of the brain stem. Pick out.
- A.
Forebrain and midbrain
- B.
Midbrain and hindbrain
- C.
Forebrain and hindbrain
- D.
Forebrain and spinal cord
Correct Answer
B. Midbrain and hindbrainExplanation
The correct answer is midbrain and hindbrain. The brain stem is the part of the brain that connects the spinal cord to the higher brain regions. It consists of three main parts: the midbrain, the pons, and the medulla oblongata. The midbrain is responsible for relaying sensory and motor information, while the hindbrain controls basic functions such as breathing, heart rate, and balance. Therefore, both the midbrain and hindbrain are part of the brain stem.Rate this question:

Spinal nerves are ________.
- A.
Sensory nerves
- B.
Motor nerves
- C.
Mixed nerves
- D.
Innervating the brain
Correct Answer
C. Mixed nervesExplanation
Spinal nerves are mixed nerves because they contain both sensory and motor fibers. These nerves carry information from the body to the brain (sensory function) and also transmit signals from the brain to the muscles and organs (motor function).Rate this question:

An endocrine gland found in neck is ___________
- A.
Adrenal gland
- B.
Pituitary gland
- C.
Thyroid gland
- D.
Pancreas
Correct Answer
C. Thyroid glandExplanation
The correct answer is the thyroid gland. The thyroid gland is an endocrine gland located in the neck. It produces hormones that regulate metabolism and growth. It plays a crucial role in controlling various bodily functions, including heart rate, body temperature, and energy levels. Dysfunction of the thyroid gland can lead to conditions such as hypothyroidism or hyperthyroidism, which can have a significant impact on overall health and well-being.Rate this question:

An endocrine gland that is both exocrine and endocrine is _______
- A.
Pancreas
- B.
Pituitary
- C.
Thyroid
- D.
Adrenal
Correct Answer
A. PancreasExplanation
The pancreas is an endocrine gland that is both exocrine and endocrine. It functions as an exocrine gland by producing and releasing digestive enzymes into the small intestine to aid in the digestion of food. At the same time, it also acts as an endocrine gland by secreting hormones such as insulin and glucagon into the bloodstream to regulate blood sugar levels. This dual function of the pancreas makes it unique among other endocrine glands.Rate this question:

Normal blood glucose level in 100 ml of blood is _________
- A.
80-100 mg
- B.
80-120 mg
- C.
80-100 mg
- D.
70-120 mg
Correct Answer
B. 80-120 mgExplanation
The normal blood glucose level in 100 ml of blood is 80-120 mg. This range is considered to be within the normal range for blood glucose levels. Glucose is the main source of energy for the body, and maintaining a stable blood glucose level is important for overall health. Levels below 80 mg or above 120 mg may indicate a potential health issue such as hypoglycemia or hyperglycemia.Rate this question:

The “T” lymphocytes are differentiated to resist infection in _____
- A.
Parathyroid gland
- B.
Lymph gland
- C.
Thymus gland
- D.
Adrenal gland
Correct Answer
C. Thymus glandExplanation
The "T" lymphocytes, also known as T cells, are a type of white blood cell that plays a crucial role in the immune response. These cells are differentiated, or specialized, in the thymus gland. The thymus gland is responsible for the maturation and education of T cells, where they learn to recognize and respond to specific antigens. Therefore, the correct answer is the thymus gland.Rate this question:

In Meiosis-I, the pairing of homologous chromosomes takes place during the _____ stage.
- A.
Leptotene
- B.
Zygotene
- C.
Pachytene
- D.
Diplotene
Correct Answer
B. ZygoteneExplanation
In Meiosis-I, the pairing of homologous chromosomes takes place during the Zygotene stage. During this stage, the chromosomes start to condense and become visible under a microscope. They begin to pair up and align with their corresponding homologous chromosome, a process known as synapsis. This pairing is essential for the exchange of genetic material between the homologous chromosomes, which occurs in the subsequent stages of meiosis.Rate this question:
