What structure provides the spinal cord protection in a pig?

What structure provides the spinal cord protection in a pig?

The spinal cord is protected by the three layers of tissue, called spinal meninges, which surround the cord. The dura mater is the outermost layer, and it forms a tough protective coating.

What is the function of the cerebrum in a fetal pig?

The cerebrum mainly functions with sensory and motor functions and is also associated with memory and reasoning. In the pig, it is much smaller than in the human. The longitudinal fissure separates the right and left hemispheres.

What is the function of the spinal cord in the brain?

The spinal cord is a long, tube-like band of tissue. It connects your brain to your lower back. Your spinal cord carries nerve signals from your brain to your body and vice versa. These nerve signals help you feel sensations and move your body.

How does a pigs nervous system work?

Autonomic Nervous System This is the involuntary nervous system of the pig. It has separate nerves controlling all of the pig’s involuntary functions. This system partly controls the heart beat, movement of the muscular walls of the digestive system, the hormonal systems, and the excretory systems.

What is the purpose of dissecting a fetal pig?

Through a fetal pig dissection, students can develop a better understanding of the: cardiovascular or circulatory system – through the identification & study of body parts such as the left and right ventricles of the heart, aorta, renal artery and vein, pulmonary artery, pericardium, superior vena cava, etc.

What is the function of the frontal lobes?

The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions. Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control one’s responses in order to achieve a goal.

What are the two dominant systems in the abdominal cavity fetal pig?

The cavity is dominated by the liver (large, brown organ at anterior of cavity) and the small intestine, but the large intestine may not be visible.

What are the 3 functions of the spinal cord?

What does the spinal cord do?

  • Motor Functions – directs your body’s voluntary muscle movements.
  • Sensory Functions – monitors sensation of touch, pressure, temperature and pain.
  • Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).

What are midbrain functions?

midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum. The midbrain serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing.

What is the function of the pigs endocrine system?

Endocrines or hormones are the substances produced by various glands, which are carried by blood or other body fluids to influence and control the pigs metabolism.

What are the body parts of the pig?

There are between four and six primal cuts, which are the large parts in which the pig is first cut: the shoulder (blade and picnic), loin, belly (spare ribs and side) and leg. These are often sold wholesale, as are other parts of the pig with less meat, such as the head, feet and tail.

What is the purpose of dissecting?

Dissection (from Latin dissecare “to cut to pieces”; also called anatomization) is the dismembering of the body of a deceased animal or plant to study its anatomical structure. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans.
